speech synthesizer online

Voice   Generator

This web app allows you to generate voice audio from text - no login needed, and it's completely free! It uses your browser's built-in voice synthesis technology, and so the voices will differ depending on the browser that you're using. You can download the audio as a file, but note that the downloaded voices may be different to your browser's voices because they are downloaded from an external text-to-speech server. If you don't like the externally-downloaded voice, you can use a recording app on your device to record the "system" or "internal" sound while you're playing the generated voice audio.

Want more voices? You can download the generated audio and then use voicechanger.io to add effects to the voice. For example, you can make the voice sound more robotic, or like a giant ogre, or an evil demon. You can even use it to reverse the generated audio, randomly distort the speed of the voice throughout the audio, add a scary ghost effect, or add an "anonymous hacker" effect to it.

Note: If the list of available text-to-speech voices is small, or all the voices sound the same, then you may need to install text-to-speech voices on your device. Many operating systems (including some versions of Android, for example) only come with one voice by default, and the others need to be downloaded in your device's settings. If you don't know how to install more voices, and you can't find a tutorial online, you can try downloading the audio with the download button instead. As mentioned above, the downloaded audio uses external voices which may be different to your device's local ones.

You're free to use the generated voices for any purpose - no attribution needed. You could use this website as a free voice over generator for narrating your videos in cases where don't want to use your real voice. You can also adjust the pitch of the voice to make it sound younger/older, and you can even adjust the rate/speed of the generated speech, so you can create a fast-talking high-pitched chipmunk voice if you want to.

Note: If you have offline-compatible voices installed on your device (check your system Text-To-Speech settings), then this web app works offline! Find the "add to homescreen" or "install" button in your browser to add a shortcut to this app in your home screen. And note that if you don't have an internet connection, or if for some reason the voice audio download isn't working for you, you can also use a recording app that records your devices "internal" or "system" sound.

As an author I have written numerous books but have been limited by my inability to write them in other languages period now that I have found 11 labs, it has allowed me to create my own voice so that when writing them in different languages it's not someone else's voice but my own.

@MURFAISTUDIO

Hear from Our Customers

Murf allows me to create TTS voiceovers in a matter of minutes. Previously, I had a tedious process of sending scripts out to agencies and waited days to get voiceovers back. With Murf, I can make changes whenever I like, diversify my speaker portfolio by picking new voices instantly, and even ramp up my course localization.

Murf it's an amazing text-to-speech AI voice generator, easy to work with, flexible and reliable. Its voices, non-pro and pro (either English, Spanish, and French), are both so real that many clients of mine have been surprised to know that they were not from professional voice-over actors.

I recently tried murf.ai and I have to say I am thoroughly impressed. The quality of the generated voice is exceptional and very realistic, which is important for my business needs. The platform is user-friendly and easy to navigate, and the range of voices available is impressive.

This website is so easy and clear that you will find yourself mastering all the tools in no time. The fact that regenerating the voice with different voices, punctuations, and tones does not deduct from your allowed minutes is so fair and reasonable. And the price is affordable too. Highly recommended

This is the most human-like voice I was able to find. It's very lively,and I found it suitable for many types of videos including marketing and e-learning, it kept my audience engaged!

I just started to create a video channel about historical figures, and Murf.ai really brings them to life. I found my top voice for my scripts, and the easy integration of video elements makes it a breeze to create informative videos. I also like the easy changes one can make to the tone of voice from within the editor.

Frequently Asked Questions

Text to speech: what is it and how does it works.

In essence, text to speech is the generation of synthesized speech from text. It was primarily designed as an assistive technology to help individuals with hearing impairments, visual and learning disabilities, and aged citizens to understand and consume content in a better manner. Today, the applications of TTS systems have grown manifold, and range from content creation to voiceover generation to customer service, and more. With a touch of a button, TTS can take words on a computer or other digital device and convert them into audio files. Today, the technology is used to create narratives for explainer videos or product demos , turn a book into an audio book, generate voiceovers for elearning materials, training videos, ads and commercials, YouTube videos, or podcasts, among other things.

How does TTS work?

Text to speech software leverages AI and deep learning algorithms to process the written input and sythesize a spoken output. The written text is first broken down into individual words and phrases by the TTS software’s text analysis component and then various rules and algorithms are applied to determine the appropriate pronunciation, inflection, and emphasis for each word. The speech synthesis component of the software then takes this information along with pre-recorded sound samples of individual phonemes and uses it to generate the spoken words and sentences, which is then spoken out loud using a synthesized voice generated by a computer or other device. 

Top Five Use Cases of Text to Speech Software

From increasing brand visibility and customer traction to improving customer service and boosting customer engagement to helping people with visual impairments, reading difficulties, and learning disabilities, text to speech is proving to be a game-changing technology across industries. 

Considering the myriad of benefits offered by TTS technology and how simple they make information retention, businesses are integrating text to speech into their workflow in one form or another. Here is a glimpse of all the ways text to speech is currently being utilized:

TTS in Assistive Technology 

For quite some time now, text to speech software has been used as an accessibility tool for individuals with a variety of special needs linked to Dyslexia, visual impairments, or other disabilities that make it difficult to read traditional text. Using TTS platforms, people facing such problems can convert text to speech and learn by listening on the go. Text to speech solutions also improves literacy and comprehension skills. When used in language education, they can make learning more engaging. For example, it's much easier and faster to apprehend a foreign language when listening to the live translation of written words with correct intonation and pronunciation than when reading. 

TTS in Translations

Given the fact that modern text to speech solutions come with multilingual support, brands can reach local customers by converting their content from text to audio in the local language. This will help target and connect with native-speaking customers or audiences in remote areas. 

Furthermore, text to speech solutions can also be used to translate content from one language to another. This is especially beneficial for users who come across a piece of content in a language they don't understand and can have it read aloud in their native language or a language they are adept at for better understanding.

TTS in Customer Service

With advancements in speech synthesis, it has become easier to create text and convert it to pre-recorded voices for interactive voice response calls. Today's TTS technology comes with human-like AI voices that can make natural human conversations on IVR calls. This helps contact centers provide personalized customer interactions without requiring assistance from live agents. 

TTS serves as both an inbound and outbound customer service tool. For example, when used in tandem with an IVR system, TTS solutions can provide personalized information to callers, such as greeting a customer by name, providing account information, confirming details about the order, payment, or appointment, and more. Furthermore, by tapping into the extensive range of languages, accents, and a wide variety female and male voices offered by TTS software, companies can provide an experience that matches their customer's profiles or help promote an image for their brand. 

TTS in Automotive Industry

Text to speech solutions help make connected and autonomous cars safer and sound truly unique, begetting an on-road revolution. They can be used in in-car conversational systems for navigational prompts and map data, infotainment systems to read aloud information about the car, such as fuel level or tire pressure, and swap music and voice assistants to place phone calls, read messages, and more.

TTS in Healthcare

In the healthcare industry, text to speech solutions can be used to read aloud patient information, instructions for taking medication, and provide information to doctors and other medical professionals about upcoming appointments, scheduling calls, and more. 

Why text to speech matters for businesses?

It's an exciting time to stake your claim in the realm of speech synthesis. There are a number of key industries where the text to speech technology has already succeeded in making a dent. Here are a few different ways in which businesses can harness the power of text to speech and save money and time:

Enhances customer experience

Any business can leverage TTS to alleviate human agent workload and offer customized conversational customer support. By integrating these solutions with IVR systems, companies can automate customer interactions, facilitate smart and personalized self-service by providing voice responses in the customer's language and remove communication barriers. Furthermore, organizations can also use TTS to make AI-enabled routine calls to inform customers about promotional offers, payment reminders, and much more. That said, by using text to speech in voice-activated chatbots, businesses can provide customers, especially the visually impaired, with a more immersive experience, thereby enriching the customer experience.

Global market penetration

Text to speech solutions offer synthetic voices in multiple languages enabling businesses to create content in several different languages and reach customers across different countries worldwide. Organizations can build trust with customers by creating voiceovers for ads, commercials, product demos, explainer videos, and PowerPoint presentations, among other content pieces in regional dialects and native languages. 

Increases Web Presence

That said, with the help of TTS solutions, businesses can provide an audio version of their content in addition to a written version, enabling more accessibility to a broader audience, who can choose whether to read or listen to it based on their preferences. This increases the brand's web presence. Moreover, using text to speech, brands can create a familiar, recognizable and unique voice across all their voice channels, making it easy for customers to identify the brand the second they hear it. This way, the brand shows up everywhere and improves its web presence.

Who else can benefit from text to speech?

Today’s online text to speech systems can generate speech that is almost indistinguishable from a human voice, making them a valuable tool for a wide range of applications, from improving accessibility for people with disabilities to providing convenient and efficient ways to communicate information.

Here is a list of everybody that can benefit immensely from using best text to speech softwares for their content and voiceover needs:

Many educators struggle to enhance the value of their curriculum while simplifying their workloads. This is where realistic text to speech technology plays a key role. Firstly, it improves accessibility for students with disabilities. Screen readers and other tools which are speech enabled can make learning an equal opportunity and enjoyable experience for those with learning and physical disabilities. Secondly, it helps teach comprehension in an effective manner. Text to speech software offers an easy way for students to listen to how words are spoken in their natural structure and following the same is easier through audio playback.

TTS software also enhances engagement and makes learning interesting for students. For example, using natural sounding text to speech voices, teachers can create engaging presentations and elearning modules that capture student’s attention. 

In marketing specifically, text to speech technology can help improve data collection, facilitate comprehensive customer profiling, and better data analysis. Online text to speech tools offer an easy way for businesses to reach a broader audience and create customized user experiences.

For instance, marketing teams can create and deliver videos to prospective clients to establish a connection and brief them on queries and complicated products or services in the language and accent the customer is comfortable with. Furthermore, AI voices enable marketing teams to create crisp, high quality professional-sounding voiceovers in a few simple steps without hiring voice actors or requiring any professional recording studios.

Text to speech generators offer authors numerous advantages. One, it serves as an editing aid and helps storytellers proof read their novels and manuscripts to identify grammatical errors and other mistakes in their drafts before publishing. Listening to their stories being read aloud also allows authors to gauge the response to their work on other people. Authors can also use realistic voice generators to convert their books into audiobooks and podcasts and broaden the reach of their work. 

From interviews about true crime to politics and science, there are all sorts of popular podcast formats today. And, regardless of how good your podcast topic is, it won’t matter if the host doesn’t have a good voice. That said, not everyone can have that best podcast voice like an old-school radio anchor or a news presenter. This is where text to speech platforms come in. You don’t have to record scripted intros, prologues, or epilogues, an AI narrator can do it for you. Through text to speech software, you can automatically create the narrative and voiceover for your podcast in the language and tone you want in a matter of minutes by simply uploading the script to the platform. 

Creating good voice overs for your animated explainer videos or product demos or games typically meant investing a lot of money on recording equipment and hiring professional voice actors. Not anymore. With AI text to speech platforms, you can add natural sounding voices to your animated video to make them more engaging and captivating.

What is an AI Voice Generator?

An AI voice generator is a state-of-the-art technology that uses artificial intelligence (AI) to create voice recordings or speech that sounds human. These systems synthesize natural-sounding speech by analyzing large datasets of human voices through deep learning algorithms. AI voice generators can be used for various tasks, such as creating text-to-speech conversion solutions and voiceovers for movies and screen captures. They make producing high-quality audio content straightforward since they can imitate various accents, languages, and speech patterns. With its realistic and adaptable AI-generated voices, this technology revolutionizes sectors like accessibility services, media production, and content creation.

What is an AI Voice?

AI voice refers to a synthetic or computer-generated voice created using sophisticated algorithms and machine learning models. The AI voices' emulation of human voices makes speaking convincingly and naturally possible. Text-to-speech software, voice assistants, virtual CSRs, and content production are just a few of the industries they find use in. AI voices are flexible tools for information delivery, improving user experiences, and automating spoken communication chores since they can be tailored for various accents, languages, and tones.

How Do AI Voice Generators Work?

AI voice synthesizers use neural networks and deep learning techniques to mimic human speech. At first, these AI voice generators are trained on large datasets of human voice recordings to acquire phonemes, intonations, and speech patterns. After training, these models can anticipate the best phonetic and prosodic components to turn text input into synthetic voice. Pitch, tone, and tempo can all be changed to produce a variety of voices. Certain models (e.g., Synthesys) produce natural speech by combining phoneme sequences with text. With its natural-sounding synthetic voice, the output can be utilized for many purposes, such as voiceovers and text-to-speech. Here's a detailed rundown of how they function: Text processing — Written text is fed into the system at the start. This content may be presented in paragraphs, phrases, or even longer papers. Text analysis — The AI voice generator analyzes the text to determine its linguistic structure, including word order, punctuation, and grammar conventions. Sentence boundaries, parts of speech, and other linguistic components are also be identified at this step. Phonetic conversion — The AI then determines the text's phonetic representation. This entails dissecting words into their constituent phonemes, a language's smallest sound units. Voice selection — Selecting from various voices, dialects, and accents is the next option for the user, depending on the particular AI voice generator. The AI model that generates the voice can significantly impact the output's naturalness and quality. Natural Language Processing — The AI uses natural language processing techniques to comprehend semantics and context. This aids in choosing the proper tempo, stress, and intonation—all of which are essential for the generated speech to sound realistic. Voice synthesis — Combining phonetic components, prosody (intonation, rhythm, and pitch), and language context allows the AI to produce speech. The audio waveform is generated by deep learning models such as Transformer-based architectures, Convolutional Neural Networks (CNNs), and Recurrent Neural Networks (RNNs). Audio rendering — The audio waveform is then created from the synthesized speech. The digital audio data that can be played on speakers or headphones is represented by this waveform. Output — Delivering the created audio to the user is the last stage. This could take the shape of an audio file that can be downloaded, audio that can be streamed, or an application or service integration. Customization — customization is a key feature of modern AI voice generators. Users now have the ability to tweak elements like speech speed, pauses, pitch, and tone to better suit their preferences. These customization options have opened up new possibilities for users to personalize their AI-generated voices. Integration — integration is another exciting aspect of AI voice generators. These systems can seamlessly integrate into a range of applications, from virtual assistants and accessibility tools to e-learning platforms and content creation software. This integration capability makes AI-generated voices a valuable addition to various fields, enhancing the user experience in each of these areas. Over the past few years, AI voice generators have made significant advancements, resulting in remarkably natural-sounding speech. They have found their footing in diverse sectors, including education, entertainment, accessibility, and customer service. This progress has made synthetic speech that closely resembles human speech more accessible and adaptable than ever before.

How Long Does It Take To Synthesize Text to Speech?

Text complexity, speech synthesis engine performance, and text length are some variables that affect how long it takes to synthesize text into speech. Modern AI-based text-to-speech systems can produce speech for short to medium-length texts almost instantly, usually in a few seconds. However, the synthesis process may take a little longer—typically a few seconds to a minute—for longer and more complicated texts. Advances in AI technology have significantly shortened the time required for text-to-speech conversion, making it a quick and efficient process for various applications, including voice assistants and content production.

How is Voice Generation Time Calculated?

The text's intricacy, the AI voice model's quality, and the hardware's processing capacity affect how long it takes to generate an audio file. Since it's usually monitored in real-time, processing a minute's worth of voice creation takes roughly a minute. Dedicated gear and speedier CPUs, though, can expedite the procedure. Furthermore, cloud-based AI services could provide different processing speeds depending on server traffic. Longer texts and more complex voice models will also lengthen the generation time. In conclusion, real-time processing is the baseline, while text complexity, software, and hardware affect generation time.

Why Should I Use An AI Voice Generator Instead Of Hiring Voice Artists?

AI voice generators provide economical and practical options for content creation and voiceovers. They save time and money by offering instant access to various voices, languages, and accents. AI speech generators can produce content in minutes instead of paying professional voice actors; therefore, projects can be completed quickly. They also provide possibilities for pitch, tone, and pause adjustments, as well as speed, pronunciation, and emotions, resulting in adaptable and realistic-sounding results. Professional voice actors provide a personal touch, but AI voice generators are a realistic option for content creators seeking quality and ease, especially when working on tight deadlines or budgets.

What is text to speech

Text to speech, also known as TTS, read aloud, or even speech synthesis . It simply means using artificial intelligence to read words aloud be; it from a PDF , email, docs, or any website. There isn’t a voice artist recording phrases or words, or even the entire article. Speech generation is done on-the-fly, in real time, with natural sounding AI voices.

And that’s the beauty of it all. You don’t have to wait. You simply press play and artificial intelligence makes the words come alive instantly, in a very natural sounding voice. You can change voices and accents across multiple languages.

Listen to any article. Easily scan any printed material and convert the image to audio.

I used to hate school because I’d spend hours just trying to read the assignments. Listening has been totally life changing. This app saved my education.

Ana Student with Dyslexia

Speechify has made my editing so much faster and easier when I’m writing. I can hear an error and fix it right away. Now I can’t write without it.

With Speechify’s API, we can offer our users a new and accessible way to consume our content. We’ve seen that readers who choose to listen to articles with Speechify are on average 20% more engaged than users who choose not to listen.

Susy Botello

Thanks for sharing this.I love this feature. I just tweeted at you on how much I like it. The voice is great and not at all like the text-to-speech I am used to listening to. I am a podcaster and I think this will help a lot of people multitask a bit, especially if they are interrupted with incoming emails or whatever. You can read-along but continue reading if your eyes need to go elsewhere. Hope you keep this. It’s already in other web publications. I also see it in some news sites. So I think it could become a standard that readers expect when they read online. Can I vote twice?

Renato Vargas

I just started using Medium more and I absolutely love this feature. I’ve listened to my own stories and the Al does the inflections just as I would. Many complain that they can’t read their own stories, but let’s be honest. How many stories would go without an audio version if you had to do all of them yourself? I certainly appreciate it. Thanks for this!!

Oh! How cool – I love it 🙂 The voice is surprisingly natural sounding! My eyes took a much appreciated rest for a bit. I’ve been a long time subscriber to Audible on Amazon. I think this is Great 🙂 Thank you!

Paola Rios Schaaf

Super excited about this! We are all spending too much time staring at our screens. Using another sense to take in the great content at Medium is awesome.

Hi Warren, I am one of those small, randomly selected people, and I ABSOLUTELY love this feature. I have consumed more ideas than I ever have on Medium. And also as a non-native English speaker, this is really helping me to improve my pronunciation. Keep this forevermore! Love, Ananya:)

This is the single most important feature you can role out for me. I simply don’t have the time to read all the articles I would like to on Medium. If I could listen to the articles I could consume at least 3X the amount of Medium content I do now.

Andrew Picken

Love this feature Warren. I use it when I’m reading, helps me churn through reading and also stay focused on the article (at a good speed) when my willpower is low! Keeping me more engaged..

I was THRILLED the other day when I saw the audio option. I didn’t know how it got there, but I pressed play, and then I was blown away hearing the words that I wrote being narrated

Neeramitra Reddy

LOVE THISSS. As someone who loves audio almost as much as reading, this is absolute gold

What is text to speech (TTS)?

Text-to-speech goes by a few names. Some refer to it as TTS,  read aloud , or even speech synthesis ; for the more engineered name. Today, it simply means using  artificial intelligence  to read words aloud be; it from a PDF, email, docs, or any website. Instantly turn text into audio. Listen in English, Italian, Portuguese,  Spanish , or more and choose your accent and character to personalize your experience.

How does AI text to speech work?

Beautifully. Speech synthesis works by installing an app like Speechify either on your device or as a browser extension. AI scans the words on the page and  reads it out loud , without any lag. You can change the default voice to a custom voice, change accents, languages, and even increase or decrease the speaking rate.

AI has made significant progress in synthesizing voices. It can pick up on formatted text and change tone accordingly. Gone are the days where the voices sounded  robotic . Speechify is revolutionizing that.

Once you install the TTS mobile app, you can easily convert text to speech from any website within your browser, read aloud your email, and more. If you install it as a  browser extension , you can do just the same on your laptop. The web version is OS agnostic. Mac or Windows, no problem.

What is the text-to-speech service?

A text-to-speech service is a tool, like Speechify text to speech, that transforms your written words into spoken words. Imagine typing out a message and having it read out loud by a digital voice – that’s what TTS services, like Speechify TTS do.

What are the benefits of text to speech?

TTS technology offers many benefits, like helping those with reading difficulties, providing rest for your eyes, multitasking by listening to content, improving pronunciation and language learning, and making content accessible to a wider audience.

How is Speechify TTS better than Murf AI text to speech, Google Voice, or TTSReader?

Speechify TTS stands out by offering a more natural and human-like voice quality, a wider range of customization options, and user-friendly integration across devices. Plus, our dedication to accessibility means that we ensure a seamless and inclusive experience for all users.

How to use our text to speech (tts) tool.

A text-to-speech reader has the function of reading out loud any text you input. Our tool can read text in over 50 languages and even offers multiple text-to-speech voices for a few widely spoken languages such as English.

• Step #1 : Write or paste your text in the input box. You also have the option of uploading a txt file.
• Step #2 : Choose your desired language and speaker. You can try out different speakers if there are more available and choose the one you prefer.
• Step #3 : Choose the speed of reading. You can set up the text to be read out loud faster or slower than the default.
• Step #4 : Choose the font for the text. We recommend a smaller font if you have a large text and want to avoid scrolling, or a bigger font to follow the text while easily read aloud.
• Step #5 : Tick the “I’m not a robot” checkbox in the bottom right of the screen.
• Step #6 : Press the play button on the bottom of the text box to hear your text read out loud.
• Step #7 : Get a share link for the resulting audio file or download it as an mp3. Our tool generates high quality TTS that is easy to understand by everyone.

Choose from 50 languages

Our free text to speech tool offers various languages and natural sounding voices to choose from. We made an effort to make our TTS reader available for as many people as possible by including the most commonly spoken languages worldwide.

We have languages available for the following regions:

• Middle East
• South-East Asia
• Middle Asia (India)
• North America

Benefits of using text to speech

TTS is widely used as assistive technology that helps people with reading and visual impairments understand a text. For example:

• Visually impaired individuals greatly benefit from having a program read texts out loud to them.
• Dyslexic individuals will also benefit from a text to talk reader because they can understand texts more easily.
• Children with reading impairments can use text readers to understand lessons easier.
• A text to voice tool is also of great help for people with severe speech impairments. Our web browser TTS tool allows them to type what they want to say and instantly play the audio to the person they wish to communicate with.

Other benefits of reading text aloud:

• People learning or communicating in non-native languages can use text to speech as a tool for learning how to spell words correctly and express themselves fluently in their desired language. It’s beneficial when traveling to a country where that language is spoken, and one wants to communicate with locals in their native language.
• Younger people in multilingual families might find it challenging to communicate with grandparents who still reside in their native countries. Text to speech can bridge the linguistic gap and help strengthen family bonds.
• Muti-taskers and busy people, in general, can use text to speech online to get the latest news.

What is text to speech?

Text to speech is a tool or program that takes text or words input by the user and reads them out loud. It’s used as an assistive technology for people with reading, visual and speech impairments and as a productivity tool.

How does text to speech work?

Text to speech tools use speech synthesis to read texts out loud. The simplest form of speech synthesis uses snippets of human speech to deliver a coherent and natural-sounding message. These snippets are taken from vast libraries of human sounds, words, phrases etc., and they can be used to verbalize almost anything digitally.

Different browsers and operating systems have different voices (typically including male and female voices and foreign accents), so look at the options in the dropdown box to see what voices are available.

Please note, as this is very new technology, the voice generator is currently only compatible with the latest version of Chrome or Safari. Firefox and Internet Explorer are not currently supported.

Mac computers come with several voices included as part of the MacInTalk system. These voices appear frequently in popular culture, such as in the song "Satisfaction" by Benny Benassi (which uses Fred and Victoria), or Auto in Wall-E which uses a combination of Ralph and Zarvox.

meSpeak.js (modulary enhanced speak.js) is a 100% client-side JavaScript text-to-speech library based on the speak.js project, a port of the eSpeak speech synthesizer from C++ to JavaScript using Emscripten. meSpeak.js adds support for Webkit and Safari and introduces loadable voice modules. Also there is no more need for an embedding HTML-element. Separating the code of the library from voice definitions should help future optimizations of the core part of speak.js . All separated data has been compressed to base64-encoded strings from the original binary files to save some bandwidth (compared to JS-arrays of raw 8-bit data). All separated data has been compressed to base64-encoded strings from the original binary files to save some bandwidth (compared to JS-arrays of raw 8-bit data). Browser requirements: Firefox, Chrome/Opera, Webkit, and Safari (MSIE11 is expected to be compliant). meSpeak.js 2011-2020 by Norbert Landsteiner, mass:werk – media environments; https://www.masswerk.at/mespeak/

GNU General Public License The eSpeak text-to-speech project is licensed under version 3 of the GNU General Public License. Since meSpeak.js incorporates eSpeak, the same license (GPL v.3) applies.

Important Changes:

v 2.0 Major Upadate — Introducing a web worker for rendering the audio concurrently (outside the UI thread), reduced file size, basic audio filtering and stereo panning, and a new, simplified loading scheme for loading voice/language definitions. v 2.0.1 Added meSpeak.getAudioAnalyser() , because, why not? v 2.0.2 Disabled workers on mobile diveses. v 2.0.3 Changed implementation of meSpeak.getAudioAnalyser() . v 2.0.4 Added a simple mobile unlocker (initial touchstart event handler). (v. 2.0.5 Added the original eSpeak license statement.) v 2.0.6 Added a workaround an issue with some browsers after the 80 th call. v 2.0.7 Added audio unlocking for Safari desktop browsers.

Some real world examples (at masswerk.at): • Explore client-side speech I/O with E.L.I.Z.A. Talking • Celebrating meSpeak.js v.1.5: JavaScript Doing The JavaScript Rap (featuring MC meSpeak) (a heavy performance test) • Celebrating meSpeak.js v.2.0: MeSpeak.js Stereo Panning Demo (reading a dialog by distributed roles) • Audio Anaylser Demo , a simple oscilloscope display for meSpeak.js.

• MeSpeak now runs a worker in order to render any utterances, if available. (Otherwise, the core application is started in a single-threaded instance to maintain compatibility with older clients.) This means meSpeak.js will generally not block the UI thread and will also be precessing faster. Moreover, the filesize has been reduced (< 500K g-zipped) Please mind that workers are disabled for mobile devices. (Since there is no user interaction as the sound arrives from the worker on a postMessage event, the playback would be muted.)
• As a result, meSpeak.js now consists of two files, the fornt-end “ mespeak.js ” and the core application “ mespeak-core.js ”, which will be loaded automatically by the front-end. (You still have to include “ mespeak.js ” onyl, just as before.)
• A standard configuration is now included. Meaning, there is no need to call “ meSpeak.loadConfig() ” (which now does nothing) or checking meSpeak.isConfigLoaded() (which now returns always true .) However, there's now “ meSpeak.loadCustomConfig() ” to override the standard configuration.
• Voice files are now loaded relative to the script (instead of relative to the embedding page)! Also, you may now just specify a voice-ID and the respective JSON-file will be loaded from the directory “ voices ” in the same path as the application.
• In order to export a data-stream with the option “ rawdata ”, a callback has to be supplied. The stream will be returned as the third argumend (of success, id, stream) in the callback. “ meSpeak.speak() ” now always returns a 32-bit integer ID.
• There is now an additional option “ pan ” for stereo panning. Compare the Stereo Panning Demo .
• A new method “ meSpeak.setFilters() ” allows you to apply global audio filtering for prostprocessing. This may be any number of BiquadFilters or DynamicsCompressors as specified by the Web Audio API, which will be chained together and will feed into the global gain.
• The new method “ meSpeak.getAudioAnalyser() ” returns an Web Audio AnalyserNode for further processing (e.g., a wave display) of the signal played by meSpeak.js.

meSpeak.loadVoice('voices/en/en-us.json'); or just meSpeak.loadVoice('en/en-us'); meSpeak.speak('hello world'); meSpeak.speak('hello world', { option1: value1, option2: value2 .. }); meSpeak.speak('hello world', { option1: value1, option2: value2 .. }, myCallback); var id = meSpeak.speak('hello world'); meSpeak.stop(id); meSpeak.speak( text [, { option1: value1, option2: value2 .. } [, callback ]] ); text : The string of text to be spoken. The text may contain line-breaks ("\n") and special characters. Default text-encoding is UTF-8 (see the option "utf16" for other). options (eSpeak command-options): * amplitude : How loud the voice will be (default: 100) * pitch : The voice pitch (default: 50) * speed : The speed at which to talk (words per minute) (default: 175) * voice : Which voice to use (default: last voice loaded or defaultVoice, see below) * wordgap : Additional gap between words in 10 ms units (default: 0) * variant : One of the variants to be found in the eSpeak-directory "~/espeak-data/voices/!v" Variants add some effects to the normally plain voice, e.g. notably a female tone. Valid values are: "f1", "f2", "f3", "f4", "f5" for female voices "m1", "m2", "m3", "m4", "m5", "m6, "m7" for male voices "croak", "klatt", "klatt2", "klatt3", "whisper", "whisperf" for other effects. (Using eSpeak, these would be appended to the "-v" option by "+" and the value.) Note: Try "f2" or "f5" for a female voice. * linebreak : (Number) Line-break length, default value: 0. * capitals : (Number) Indicate words which begin with capital letters. 1: Use a click sound to indicate when a word starts with a capital letter, or double click if word is all capitals. 2: Speak the word "capital" before a word which begins with a capital letter. Other values: Increases the pitch for words which begin with a capital letter. The greater the value, the greater the increase in pitch. (eg.: 20) * punct : (Boolean or String) Speaks the names of punctuation characters when they are encountered in the text. If a string of characters is supplied, then only those listed punctuation characters are spoken, eg. { "punct": ".,;?" }. * nostop : (Boolean) Removes the end-of-sentence pause which normally occurs at the end of the text. * utf16 : (Boolean) Indicates that the input is UTF-16, default: UTF-8. * ssml : (Boolean) Indicates that the text contains SSML (Speech Synthesis Markup Language) tags or other XML tags. (A small set of HTML is supported too.) further options (meSpeak.js specific): * volume : Volume relative to the global volume (number, 0..1, default: 1) Note: the relative volume has no effect on the export using option 'rawdata'. * log : (Boolean) Logs the compiled eSpeak-command to the JS-console. * pan : (Number) Stereo panning, -1 >= pan <= 1 -1 represents the extreme left 1 represents the extreme right 0 center (no effect) This option is available only with clients supporting the Web Audio API. * rawdata : Do not play, return audio data (wav) in callback. (A callback, see below, has to be specified in order to retrieve the data stream.) The type of the returned data is derived from the value (case-insensitive) of 'rawdata': - ' base64 ': returns a base64-encoded string. - ' mime ': returns a base64-encoded data-url (including the MIME-header). (synonyms: 'data-url', 'data-uri', 'dataurl', 'datauri') - ' array ': returns a plain Array object with uint 8 bit data. - default (any other value): returns the generated wav-file as an ArrayBuffer (8-bit unsigned). Note: The value of 'rawdata' must evaluate to boolean 'true' in order to be recognized. callback : An optional callback function to be called after the sound output ended. function myCallback(success, id [, stream]) { ... } * success (Boolean): flag indicating the success of the operation * id (Number): 32-bit id, defaults to 0 * stream (*): data stream of the wav-file in the format specified by the "rawdata" option. Defaults to ArrayBuffer (uint8). If the resulting sound is stopped by meSpeak.stop() , the success-flag will be set to false. (A callbak may be also specified as a property of the options object. If both are present, the callback argument takes precedence.) Returns : * a 32bit integer ID greater than 0 (or 0 on failure). The ID may be used to stop this sound by calling meSpeak.stop( <id> ) . meSpeak.loadVoice('voices/fr.json', userCallback); meSpeak.loadVoice('en/en-us', userCallback); // userCallback is an optional callback-handler. The callback will receive two arguments: // * a boolean flag for success // * either the id of the voice, or a reason for errors ('network error', 'data error', 'file error') Note : Starting with meSpeak.js 2.0, voices are loaded relative to meSpeak.js . Also, if you just specify a voice-id, meSpeak.js will now try to load a respective voice from a directory "voices" in the same directory as the script. e.g., loadVoice('fr') will load ' /path/to/mespeak/ voices/fr.json', loadVoice('en/en-us') will load ' path/to/mespeak/ voices/en/en-us.json'. A newly loaded voice will always become the new default voice: meSpeak.loadVoice('fr'); alert( meSpeak.getDefaultVoice() ); // 'fr' meSpeak.setDefaultVoice('de'); Sets the default voice to the voice with the voice with the id specified. (Note: If not explicitly set the default voice is always the the last voice loaded.) if ( meSpeak.isVoiceLoaded('de') ) meSpeak.setDefaultVoice('de'); Check, if a voice has been successfully loaded. meSpeak.loadConfig() meSpeak.isConfigLoaded() Legacy methods. A standard configuration is now included in meSpeak.js. meSpeak.loadConfig() does nothing meSpeak.isConfigLoaded() returns always true However, you can still load a custom configuration using meSpeak.loadCustomConfig(url, callback) As with vocies, config-files will be loaded relative to the mespeak.js script. An optional callback will have two arguments, a boolean success flag and a message string reporting any reasons for failing the operation. A custom congiguration may include just some of the eSpeak config-files. Any files found, will overwrite the standard configurations. meSpeak.setVolume(0.5); meSpeak.setVolume( volume [, id-list] ); Sets a volume level (0 meSpeak.getVolume() ); // 0.5 meSpeak.getVolume( [id] ); Returns a volume level (0 meSpeak.canPlay(); // test for compatibility meSpeak.play( stream [, relativeVolume [, callback[, id[, pan]]]] ); Play (cached) audio streams (using any of the export formats, ArrayBuffer, array, base64, dta-URL) Arguments: stream : A stream in any of the formats returned by meSpeak.play() with the "rawdata"-option. volume : (optional) Volume relative to the global volume (number, 0..1, default: 1) callback : (optional) A callback function to be called after the sound output ended. The callback will be called with a single boolean argument indicating success. If the sound is stopped by meSpeak.stop() , the success-flag will be set to false. (See also: meSpeak.speak().) id : (optional, Number) An id to be used (default 0 => ignored.) meSpeak.play(myAudio, 1, null, mySoundId); meSpeak.stop(mySoundId); pan : (optional, Number) Stereo panning. (left) -1 >= pan <= 1 (right) Mind that this works only with clients supporting the Web Audio API. Returns : A 32bit integer ID greater than 0 (or 0 on failure). The ID may be used to stop this sound by calling meSpeak.stop( <id> ) . // exaple for caching and playing back audio streams var audiostreams = []; meSpeak.speak('hello world', { 'rawdata': true }, function(success, id, stream) { // data is ArrayBuffer of 8-bit uint audiostreams.push(stream); }); meSpeak.speak('hello again', { 'rawdata': 'array' }, function(success, id, stream) { // data is Array of 8-bit uint Numbers audiostreams.push(stream); }); meSpeak.speak('hello again', { 'rawdata': 'base64' }, function(success, id, stream) { // data is a string containing the base64-encoded wav-file audiostreams.push(stream); }); meSpeak.speak('hello yet again', { 'rawdata': 'data-url' }, function(success, id, stream) { // data is a data-URL with MIME-header "data:audio/x-wav;base64" audiostreams.push(stream); }); meSpeak.play(audiostreams[0]); // using global volume meSpeak.play(audiostreams[1], 0.75); // 75% of global volume meSpeak.play(audiostreams[2], 0, null, 0, -1); // play if from the left meSpeak.play(audiostreams[3], 0, 0, 0, 0.25); // play it from a querter to the right meSpeak.stop( [<id-list>] ); Stops the sound(s) specified by the id-list . If called without an argument, all sounds currently playing, processed, or queued are stopped. Any callback(s) associated to the sound(s) will return false as the success-flag. Arguments: id-list : Any number of IDs returned by a call to meSpeak.speak() or meSpeak.play() . Returns : The number (integer) of sounds actually stopped. meSpeak.setFilter(<options>[,<options>]); New in meSpeak 2.0: Set filters for audio playback (post processing). Supported are any of the BiquadFilters and DynamicsCompressors . You may add any number of filters, which will be chained together before feeding into the gloabel gain node. Options: type: (String) Filter type, case-insenstitive BiquadFilters: 'lowpass', 'highpass', 'bandpass', 'lowshelf', 'highshelf', 'peaking', 'notch', 'allpass' DynamicsCompressor: 'dynamicscompressor' or 'compressor' For BiquadFilters: frequency (Number) Q (Number) gain (Number) detune (Number) For DynamicsCompressors: threshold (Number) knee (Number) ratio (Number) reduction (Number) attack (Number) release (Number) // Example: meSpeak.setFilter( { type: 'highpass', frequency: 85 }, { type: 'compressor', threshold: -10, knee: 40, ratio: 5, attack: 0, release: 0.25 }, { type: 'bandpass', frequency: 500, Q: 0.125, detune: 10 } ); myAnalyserNode = meSpeak.getAudioAnalyser(); returns an Web Audio AnalyserNode for further processing (e.g., a wave display) of the signal played by meSpeak.js. The AnalyserNode mirrors the signal present in the first global audio processing stage (after individual volume/gain), but before filters. Compare the Audio Anaylser Demo . meSpeak.getRunMode(); Determine, if the client is running a concurrent worker or a single-threaded instance. Returns either the string "worker" or "instance" meSpeak.restartWithInstance(); For testing purposes only: Restart MeSpeak forcing it to use an instance instead of a worker. Returns: nothing / void.

Note on export formats , ArrayBuffer (typed array, defaul) vs. simple array: The ArrayBuffer (8-bit unsigned) provides a stream ready to be played by the Web Audio API (as a value for a BufferSourceNode), while the plain array (JavaScript Array object) may be best for export (e.g. sending the data to Flash via Falsh's ExternalInterface). The default raw format (ArrayBuffer) is the preferred format for caching streams to be played later by meSpeak by calling meSpeak.play() , since it provides the least overhead in processing.

Recommended File Layout

In order to ensure the functionality of meSpeak.js, the following layout is strongly encouraged:

mespeak/ mespeak.js # required mespeak-core.js # required voices/ # default location ca.json cs.json de.json ...

Mind that you just require thos vocie definitions which you are actually using.

meSpeak.speakMultipart() — concatenating multiple voices

Using meSpeak.speakMultipart() you may mix multiple parts into a single utterance.

See the Multipart-Example for a demo.

The general form of meSpeak.speakMultipart() is analogous to meSpeak.speak() , but with an array of objects (the parts to be spoken) as the first argument (rather than a single text):

meSpeak.speakMultipart( <parts-array> [, <options-object> [, <callback-function> ]] ) ; meSpeak.speakMultipart( [ { text: "text-1", <other options> ] }, { text: "text-2", <other options> ] }, ... { text: "text-n", <other options> ] }, ], { option1: value1, option2: value2 .. }, callback ) ;

Only the the first argument is mandatory, any further arguments are optional. The parts-array must contain a single element (of type object) at least. For any other options refer to meSpeak.speak() . Any options supplied as the second argument will be used as defaults for the individual parts. (Same options provided with the individual parts will override these defaults.) The method returns — like meSpeak.speak() — either an ID, or, if called with the "rawdata" option (in the general options / second argument), a stream-buffer representing the generated wav-file.

Note on iOS and Mobile Limitations

iOS (currently supported only using Safari) provides a single audio-slot, playing only one sound at a time. Thus, any concurrent calls to meSpeak.speak() or meSpeak.play() will stop any other sound playing. Further, iOS reserves volume control to the user exclusively. Any attempt to change the volume by a script will remain without effect. Please note that you still need a user-interaction at the very beginning of the chain of events in order to have a sound played by iOS.

Note on Options

The first set of options listed above corresponds directly to options of the espeak command. For details see the eSpeak command documentation . The meSpeak.js-options and their espeak-counterparts are ( mespeak.speak() accepts both sets, but prefers the long form):

JSON File Formats

1) Config-data: "mespeak_config.json": The config-file includes all data to configure the tone (e.g.: male or female) of the electronic voice.

{ "config": "<base64-encoded octet stream>", "phontab": "<base64-encoded octet stream>", "phonindex": "<base64-encoded octet stream>", "phondata": "<base64-encoded octet stream>", "intonations": "<base64-encoded octet stream>" }

Finally the JSON object may include an optional voice-object (see below), that will be set up together with the config-data:

{ ... "voice": { <voice-data> } }

2) Voice-data: "voice.json": A voice-file includes the ids of the voice and the dictionary used by this voice, and the binary data of theses two files.

{ "voice_id": "<voice-identifier>", "dict_id": "<dict-identifier>", "dict": "<base64-encoded octet stream>", "voice": "<base64-encoded octet stream>" }

Alternatively the value of "voice" may be a text-string, if an additional property "voice_encoding": "text" is provided. This shold allow for quick changes and testing:

{ "voice_id": "<voice-identifier>", "dict_id": "<dict-identifier>", "dict": "<base64-encoded octet stream>", "voice": "<text-string>", "voice_encoding": "text" }

Both config-data and voice-data may be loaded and switched on the fly to (re-)configure meSpeak.js.

Extendet Voice Format, Mbrola Voices

In order to support Mbrola voices and other voices requiring a more flexible layout and/or additional data, there is also an extended voice format :

{ "voice_id": "<voice-identifier>", "voice": "<base64-encoded octet stream>" "files": [ { "path", "<rel-pathname>", "data", "<base64-encoded octet stream>" }, { "path", "<rel-pathname>", "data", "<text-string>", "encoding": "text" }, ... ] }

or (using a text-encoded voice-definition):

{ "voice_id": "<voice-identifier>", "voice": "<text-string>", "voice_encoding": "text" "files": [ { "path", "<rel-pathname>", "data", "<base64-encoded octet stream>" }, { "path", "<rel-pathname>", "data", "<text-string>", "encoding": "text" }, ... ] }

Only a valid voice-definition is required and optionally an array "files" which may be empty or contain any number of objects, containing a property "path" (relative file-path from the espeak-data-directory) and a property "data" , containing the file (either as base64-encoded data or as plain text, if there is also an optional property "encoding": "text" ).

In order to facilitate the use of Mbrola voices, for any "voice_id" beginning with "mb/mb-" only the part following the initial "mb/" will be used as the internal identifyer for the meSpeak.speak() method. (So any given voice_id "mb/mb-en1" will be translated to a voice "mb-en1" automatically. This applies to the speak-command only.)

Please don't ask for support on Mbrola voices (I don't have the faintest idea). Please refer to Mbrola section of the eSpeak documentation for a guide to setting up the required files locally. It should be possible to load these into meSpeak.js using the "extended voice format", since you may put any additional payload into the files-array. Please mind that you will still require a text-to-phoneme translator as stated in the eSpeak documentation (this is out of the scope of meSpeak.js).

Deferred Calls

In case that speak() is called before any voice data has been loaded, the call will be deferred and executed after set up. See this page for an example. You may reset the queue manually by calling

meSpeak.resetQueue();

Amplitude and Volume

There are now two separate parameters or options to control the volume of the spoken text: amplitude and volume. While amplitude affects the generation of the sound stream by the TTS-algorithm, volume controls the playback volume of the browser. By the use of volume you can cache a generated stream and still provide an individual volume level at playback time. Please note that there is a global volume (controlled by setVolume() ) and an individual volume level relative to the global one. Both default to 1 (max volume).

Notes on Chinese Languages and Voices

Please note that the Chinese voices do only support Pinyin input (phonetic transcript like " zhong1guo2 " for 中 + 国, China) for "zh" and simple one-to-one translation from single Simplified Chinese characters or Jyutping romanised text for "zh-yue".

The eSpeak documentation provides the following notes:

*) zh (Mandarin Chinese) : This speaks Pinyin text and Chinese characters. There is only a simple one-to-one translation of Chinese characters to a single Pinyin pronunciation. There is no attempt yet at recognising different pronunciations of Chinese characters in context, or of recognising sequences of characters as "words". The eSpeak installation includes a basic set of Chinese characters. More are available in an additional data file for Mandarin Chinese at: http://espeak.sourceforge.net/data/.

**) zh-yue (Cantonese Chinese, Provisional) : Just a naive simple one-to-one translation from single Simplified Chinese characters to phonetic equivalents in Cantonese. There is limited attempt at disambiguation, grouping characters into words, or adjusting tones according to their surrounding syllables. This voice needs Chinese character to phonetic translation data, which is available as a separate download for Cantonese at: http://espeak.sourceforge.net/data/. The voice can also read Jyutping romanised text.

For a simple zh-to-Pinyin translation in JavaScript see: https://www.masswerk.at/mespeak/zh-pinyin-translator.zip

Flash-Fallback for Wave Files

(m)eSpeak produces internally wav-files, which are then played. Internet Explorer 10 supports typed arrays (which are required for the binary logic), but does not provide native playback of wav-files. To provide compatibility for this browser, you could try the experimental meSpeak Flash Fallback .

About speak.js

speak.js is 100% clientside JavaScript. " speak.js " is a port of eSpeak , an open source speech synthesizer, which was compiled from C++ to JavaScript using Emscripten . The project page and source code for this demo can be found here . Note: There had been initially plans to merge this project with speak.js, but they somehow became stuck.

• Typed arrays . The eSpeak code is not portable to the extent that would be necessary to avoid using typed arrays. (It should however be possible to rewrite small bits of eSpeak to fix that.) Typed arrays are present in Firefox, Chrome, Webkit, and Safari, but not IE or Opera.
• Update : Opposed to the state of the original documentation, newer versions of Opera and IE both provide support for typed arrays.

Mobile Navigation

Navigating the challenges and opportunities of synthetic voices.

We’re sharing lessons from a small scale preview of Voice Engine, a model for creating custom voices.

OpenAI is committed to developing safe and broadly beneficial AI . Today we are sharing preliminary insights and results from a small-scale preview of a model called Voice Engine, which uses text input and a single 15-second audio sample to generate natural-sounding speech that closely resembles the original speaker. It is notable that a small model with a single 15-second sample can create emotive and realistic voices.

We first developed Voice Engine in late 2022, and have used it to power the preset voices available in the text-to-speech API as well as ChatGPT Voice and Read Aloud . At the same time, we are taking a cautious and informed approach to a broader release due to the potential for synthetic voice misuse. We hope to start a dialogue on the responsible deployment of synthetic voices, and how society can adapt to these new capabilities. Based on these conversations and the results of these small scale tests, we will make a more informed decision about whether and how to deploy this technology at scale.

Early applications of Voice Engine

To better understand the potential uses of this technology, late last year we started privately testing it with a small group of trusted partners. We've been impressed by the applications this group has developed. These small scale deployments are helping to inform our approach, safeguards, and thinking about how Voice Engine could be used for good across various industries. A few early examples include:

• Providing reading assistance to non-readers and children through natural-sounding, emotive voices representing a wider range of speakers than what's possible with preset voices. Age of Learning , an education technology company dedicated to the academic success of children, has been using this to generate pre-scripted voice-over content. They also use Voice Engine and GPT-4 to create real-time, personalized responses to interact with students. With this technology, Age of Learning has been able to create more content for a wider audience.

1. Reference audio

2. generated audio.

• Translating content , like videos and podcasts, so creators and businesses can reach more people around the world, fluently and in their own voices. One early adopter of this is HeyGen , an AI visual storytelling platform that works with their enterprise customers to create custom, human-like avatars for a variety of content, from product marketing to sales demos. They use Voice Engine for video translation, so they can translate a speaker's voice into multiple languages and reach a global audience. When used for translation, Voice Engine preserves the native accent of the original speaker: for example generating English with an audio sample from a French speaker would produce speech with a French accent.
• Reaching global communities , by improving essential service delivery in remote settings. Dimagi is building tools for community health workers to provide a variety of essential services, such as counseling for breastfeeding mothers. To help these workers develop their skills, Dimagi uses Voice Engine and GPT-4 to give interactive feedback in each worker's primary language including Swahili or more informal languages like Sheng, a code-mixed language popular in Kenya.
• Breastfeeding
• Supporting people who are non-verbal , such as therapeutic applications for individuals with conditions that affect speech and educational enhancements for those with learning needs. Livox , an AI alternative communication app, powers Augmentative & Alternative Communication (AAC) devices that enable people with disabilities to communicate. By using Voice Engine, they are able to offer people who are non-verbal unique and non-robotic voices across many languages. Their users can choose speech that best represents them, and for multilingual users, maintain a consistent voice across each spoken language.
• Helping patients recover their voice , for those suffering from sudden or degenerative speech conditions. The Norman Prince Neurosciences Institute at Lifespan , a not-for-profit health system that serves as the primary teaching affiliate of Brown University's medical school, is exploring uses of AI in clinical contexts. They've been piloting a program offering Voice Engine to individuals with oncologic or neurologic etiologies for speech impairment. Since Voice Engine requires such a short audio sample, doctors Fatima Mirza, Rohaid Ali and Konstantina Svokos were able to restore the voice of a young patient who lost her fluent speech due to a vascular brain tumor, using audio from a video recorded for a school project.

1. Current voice

2. reference audio, 3. generated audio, building voice engine safely.

We recognize that generating speech that resembles people's voices has serious risks, which are especially top of mind in an election year. We are engaging with U.S. and international partners from across government, media, entertainment, education, civil society and beyond to ensure we are incorporating their feedback as we build. 

The partners testing Voice Engine today have agreed to our usage policies , which prohibit the impersonation of another individual or organization without consent or legal right. In addition, our terms with these partners require explicit and informed consent from the original speaker and we don’t allow developers to build ways for individual users to create their own voices. Partners must also clearly disclose to their audience that the voices they're hearing are AI-generated. Finally, we have implemented a set of safety measures, including watermarking to trace the origin of any audio generated by Voice Engine, as well as proactive monitoring of how it's being used. 

We believe that any broad deployment of synthetic voice technology should be accompanied by voice authentication experiences that verify that the original speaker is knowingly adding their voice to the service and a no-go voice list that detects and prevents the creation of voices that are too similar to prominent figures.

Looking ahead

Voice Engine is a continuation of our commitment to understand the technical frontier and openly share what is becoming possible with AI. In line with our approach to AI safety and our voluntary commitments , we are choosing to preview but not widely release this technology at this time. We hope this preview of Voice Engine both underscores its potential and also motivates the need to bolster societal resilience against the challenges brought by ever more convincing generative models. Specifically, we encourage steps like:

• Phasing out voice based authentication as a security measure for accessing bank accounts and other sensitive information
• Exploring policies to protect the use of individuals' voices in AI
• Educating the public in understanding the capabilities and limitations of AI technologies, including the possibility of deceptive AI content
• Accelerating the development and adoption of techniques for tracking the origin of audiovisual content, so it's always clear when you're interacting with a real person or with an AI

It's important that people around the world understand where this technology is headed, whether we ultimately deploy it widely ourselves or not. We look forward to continuing to engage in conversations around the challenges and opportunities of synthetic voices with policymakers, researchers, developers and creatives.
