My Voice is no longer my password —

Microsoft’s new ai can simulate anyone’s voice with 3 seconds of audio, text-to-speech model can preserve speaker's emotional tone and acoustic environment..

Benj Edwards - Jan 9, 2023 10:15 pm UTC

On Thursday, Microsoft researchers announced a new text-to-speech AI model called VALL-E that can closely simulate a person's voice when given a three-second audio sample. Once it learns a specific voice, VALL-E can synthesize audio of that person saying anything—and do it in a way that attempts to preserve the speaker's emotional tone.

Further Reading

Its creators speculate that VALL-E could be used for high-quality text-to-speech applications, speech editing where a recording of a person could be edited and changed from a text transcript (making them say something they originally didn't), and audio content creation when combined with other generative AI models like GPT-3 .

Microsoft calls VALL-E a "neural codec language model," and it builds off of a technology called EnCodec, which Meta announced in October 2022. Unlike other text-to-speech methods that typically synthesize speech by manipulating waveforms, VALL-E generates discrete audio codec codes from text and acoustic prompts. It basically analyzes how a person sounds, breaks that information into discrete components (called "tokens") thanks to EnCodec, and uses training data to match what it "knows" about how that voice would sound if it spoke other phrases outside of the three-second sample. Or, as Microsoft puts it in the VALL-E paper :

To synthesize personalized speech (e.g., zero-shot TTS), VALL-E generates the corresponding acoustic tokens conditioned on the acoustic tokens of the 3-second enrolled recording and the phoneme prompt, which constrain the speaker and content information respectively. Finally, the generated acoustic tokens are used to synthesize the final waveform with the corresponding neural codec decoder.

Microsoft trained VALL-E's speech-synthesis capabilities on an audio library, assembled by Meta, called LibriLight . It contains 60,000 hours of English language speech from more than 7,000 speakers, mostly pulled from LibriVox public domain audiobooks. For VALL-E to generate a good result, the voice in the three-second sample must closely match a voice in the training data.

On the VALL-E example website , Microsoft provides dozens of audio examples of the AI model in action. Among the samples, the "Speaker Prompt" is the three-second audio provided to VALL-E that it must imitate. The "Ground Truth" is a pre-existing recording of that same speaker saying a particular phrase for comparison purposes (sort of like the "control" in the experiment). The "Baseline" is an example of synthesis provided by a conventional text-to-speech synthesis method, and the "VALL-E" sample is the output from the VALL-E model.

While using VALL-E to generate those results, the researchers only fed the three-second "Speaker Prompt" sample and a text string (what they wanted the voice to say) into VALL-E. So compare the "Ground Truth" sample to the "VALL-E" sample. In some cases, the two samples are very close. Some VALL-E results seem computer-generated, but others could potentially be mistaken for a human's speech, which is the goal of the model.

In addition to preserving a speaker's vocal timbre and emotional tone, VALL-E can also imitate the "acoustic environment" of the sample audio. For example, if the sample came from a telephone call, the audio output will simulate the acoustic and frequency properties of a telephone call in its synthesized output (that's a fancy way of saying it will sound like a telephone call, too). And Microsoft's samples (in the "Synthesis of Diversity" section) demonstrate that VALL-E can generate variations in voice tone by changing the random seed used in the generation process.

Perhaps owing to VALL-E's ability to potentially fuel mischief and deception, Microsoft has not provided VALL-E code for others to experiment with, so we could not test VALL-E's capabilities. The researchers seem aware of the potential social harm that this technology could bring. For the paper's conclusion, they write:

"Since VALL-E could synthesize speech that maintains speaker identity, it may carry potential risks in misuse of the model, such as spoofing voice identification or impersonating a specific speaker. To mitigate such risks, it is possible to build a detection model to discriminate whether an audio clip was synthesized by VALL-E. We will also put Microsoft AI Principles into practice when further developing the models."

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.

Key Features of AI Voice Generator Software

AI voice generator software typically includes features that help users transform text, existing audio, and other media into voices with adjustable qualities to meet their needs. Additionally, many of these generative AI tools come with features to make enterprise-level collaboration and content creation run more smoothly. In general, expect to find the following features in AI voice generators:

Text to Speech

Text to speech (TTS) is a type of AI technology that changes written text into spoken audio. Most AI voice generator software allows users to upload text of different lengths and in different languages in order to generate a vocal version of the same content.

Voice Cloning

With voice cloning, AI technology can capture the content, tonality, speed, and other characteristics of a person’s voice in a recording and use that information to create a faithful replica or clone of that unique voice. With this capability, users can generate entirely new content and recordings that sound like they were spoken by that person.

Custom Voices or Voice Changing

On some AI voice platforms, if you submit your own voice clip or directly record your voice into the app, you can then change that voice into a completely different character, adjusting the tone, accent, mood, and other features. Many users want this feature for creative projects like video game development.

Multilingual Voice Library

Most generative AI voice tools give users access to a diverse, multilingual library of predeveloped voice models. Through extensive training, these TTS models are prepared to create voice transcripts and recordings that accurately adhere to each language’s specific pronunciations, tonalities, pauses, and other characteristics of that language’s speech patterns.

Dubbing and Translation

Taking TTS a step further, dubbing and translation with AI make the effort to translate an existing text or voice recording into a different spoken language. For dubbing specifically, existing recordings — often movies, commercials, and other visual media — receive a new vocal overlay, typically dubbed in a different language by an AI model.

APIs and Third-Party Integrations

With the help of APIs and built-in third-party integrations, users can more easily add AI voice creation and editing capabilities directly into their app and product development workflows. A growing number of AI voice tools are adding relevant third-party integrations to creative platforms as well as social and distribution channels.

How We Evaluated AI Voice Generators

To evaluate these AI voice generators and other leaders in this AI market sector, we looked at each tool’s standard and unique features while focusing on the following criteria. Each criterion is weighted based on its importance to the typical business user:

Vocal Quality – 30%

Needless to say, vocal quality, fidelity, and usability are the most important aspects of an AI voice generator. Within this criterion, we evaluated each tool based on the realistic quality of AI voices, the accuracy of AI voice generations, the availability of different voices and languages, and the ability to granularly edit generated voice products. We also considered whether a tool offered users the ability to customize or record their own voices and voiceovers.

Enterprise Scalability – 30%

Enterprise scalability is hugely important for AI voice generators since many companies invest in this type of platform to create global marketing, sales, and product content at scale.

For enterprise scalability, we assessed each tool’s global library of voices and dialects, its adherence to enterprise security and compliance standards, features that go beyond voice content production, collaboration and sharing capabilities, integrations with relevant third-party tools and platforms, and the scalability of APIs. We placed a special emphasis on each tool’s enterprise-level plans and the additional features that are available at this level.

Pricing – 20%

Pricing is a crucial factor when considering AI voice technology, as the cost of these tools varies widely for the features you get at that price point. As part of this evaluation, we identified whether each tool offered a free plan option, we compared how prices scale from package to package, we considered how many price points were available to users, and we looked at the value of the features added to each tier, particularly enterprise-level tiers.

Ease of Use – 20%

AI voice tools are supposed to make content creation a simpler task; for this reason, ease of use and accessibility were also important factors in how we judged each of these tools. We looked at each tool’s no-code features, the user-friendliness of voice editing tools, the quality of customer support at each subscription tier, and the availability of self-service resources and community forums for getting started and troubleshooting.

Microsoft text to speech

Table of Contents

Microsoft reigns supreme in business, gaming, and everyday computing, but can Microsoft TTS live up to the hype?

Text to speech (TTS) solutions have become an indispensable piece of assistive technology, helping countless PC users interact with the written word, be it for pleasure, school, or work. 

As you can imagine, the TTS market is somewhat saturated, with dozens of apps and browser extensions to choose from. Most of them are quite helpful, and they will do wonders for your productivity and give you a more user-friendly experience. Today, we’ll focus on Microsoft’s TTS solution — Azure.

What is Microsoft text to speech?

What is Azure, then? To answer that question, we can pose another: Do you want the power to create content with natural-sounding voiceovers or listen to your favorite pages narrated to you, with a bunch of customizable parameters that will let you adjust speech rate, tones, pronunciation, and everything else? Microsoft Azure lets you do all that — and more.

Azure is a cloud platform brimming with potential. In addition to Azure cognitive services that provide fantastic text to speech and speech-to-text solutions, you can make use of Azure cloud storage and analytics to take your productivity even further without the need to master any complicated machine learning.

Being compatible with various open-source solutions, Azure is also rather flexible. Incorporating voiceovers into custom-built apps and allowing your target audience to reap the benefits of deep machine learning has never been easier, especially with over one hundred languages and language variants Azure will put at your disposal.

How to use Microsoft’s text to speech app on your iPhone or computer

Setting Microsoft Azure up on your device is pretty straightforward, and all it takes is a few clicks to sign up at the official  Azure  website. However, if your computer usage does not extend beyond the likes of Outlook, Word, PowerPoint, Docs, and OneNote, you won’t have to download anything because those programs come with a built-in speech synthesis solution called Speak.

While it might not be a high-quality speech service, Speak comes in handy when you’re in a pinch, and it’s super easy to configure:

• Click on the Customize Toolbar option, click
• Select the More Commands options
• Click on All Commands
• Find Speak, click on it, and then click Add

Alternatives to Microsoft’s text to speech application

As we’ve mentioned in the intro, text readers are a-plenty, ranging from professional apps that will blow your mind just with their pricing to barely finished speech recognition SDKs on GitHub. If Microsoft’s text to speech voice assistant does not sound like your cup of tea, or if you’re looking for some variety, we’ve got a few alternatives that will surely tickle your fancy.

Coming in at #1 is Speechify, the top-rated TTS tool that will turn virtually anything into an audio file. It works with all Microsoft applications, and its speech models will leave you speechless. Couple that with great speech API capabilities, and you’ve got a versatile solution that will accommodate all your needs and use cases.

Amazon Polly

At #2, we’ve got Amazon Polly, a fantastic solution famous for its natural-sounding voices and plenty of speaking styles. It supports multiple languages, and its neural text to speech tech will give you plenty of customizable settings to play with whenever you want to add spice to your already authentic-sounding playbacks.

Google Cloud Text to Speech

At #3, there’s Google’s Cloud Text to Speech. Naturally, wherever there’s tech progress to be made, Google will be there, and the TTS realm is no exception. Google’s solution is all about speech synthesis markup language (SSML), and it works on a pay-per-character basis, so it’s both a useful and affordable choice if you’re working on a one-time project.

IBM Watson Text to Speech

IBM Watson takes the #4 spot. What sets Watson apart from the competition is its versatility in corporate environments. Namely, you can use it as a virtual assistant or a customer support tool and a text to speech solution. What’s more, it’s super affordable, so you won’t get a better deal elsewhere if you’re looking for something flexible.

Readspeaker 

At #5, we’ve got one of the veterans — Readspeaker. With about a quarter of a century worth of experience, Readpseaker has got TTS down to fine art. It supports over one hundred languages, and it’s fantastic for speech studios and e-learning as it can work both online and offline.

NaturalReader 

#6 is NaturalReader. This app does a great job with real-time synthesized speech, and it works with pretty much all apps you’re gonna be using on your PC. But, what earned NaturalReader a place on our list is its so-called reader mode that will purge your text of all unnecessary fluff, for example, advertisements.

VoiceDream Reader

At #7, we’ve got VoiceDream Reader, our last Microsoft Azure text to speech alternative for today. Unfortunately, while VoiceDream Reader is good for some simpler tasks, lots of users complain about a lack of accessibility and poor syncing options. But, if you need a quick solution and don’t care about the most advanced neural TTS and end-to-end tech, VoiceDream will do a decent enough job.

Is Windows 10 TTS free?

There are plenty of TTS solutions for Windows 10. Some of them are free, while others are not. The built-in Speak option that comes with Windows 10 and works in such as Outlook and Word is free, but more sophisticated solutions with custom neural voice options and other features, such as Microsoft Azure, require a subscription.

What is the most realistic TTS voice?

The most realistic TTS voices are typical of more advanced TTS tools such as Amazon Polly and Speechify. The levels of realism will depend on the language, the speech model, and the parameters of your choice.

What is the difference between Text to Speech and Voice Recognition?

While a lot of TTS programs offer both text to speech and voice recognition options, it is important not to confuse the two. Text to speech options will turn textual input into audio format, helping you engage with the text while you complete other tasks. Voice recognition, on the other, refers to an analysis of the human voice, either for the purposes of interpreting or identifying them.

7 prompts to try on Microsoft Copilot this weekend

From a vacation to festival posters

Microsoft Copilot is quickly becoming one of the most popular AI chatbots, in part because it offers much of the functionality of ChatGPT Plus for free , but also because its built into every Microsoft product.

Artificial intelligence tools like Copilot can be incredibly powerful, or they can be yet another blank canvas to stare at for hours not knowing where to start. That is the point of Prompt_Jitsu, a series of prompt ideas to get you started.

I'm a big fan of Microsoft Copilot, it builds on the core models found in ChatGPT but with a more consumer-friendly interface and control over the creativity of the output.

Fun prompts for Microsoft Copilot

I’ve tried to create a mixed set of prompts that can be adapted to fit your own needs. For example one prompt is to create a flyer for a fictional music festival you could adapt for anything from a bake sale to a kids birthday party .

1. Planning a vacation

We're going to kick things off with some light vacation planning. I've got a busy year ahead and don't see a trip on the horizon, so this is more window shopping — but it is a good chance to see how tools like Copilot can help with inspiration.

For day one it suggested I spend it in Tokyo, suggested Hotel Sunroute Plaza Shinjuku and dina at Izakaya that evening. The total trip included visits to Kyoto, Nara, Osaka, Horishima and Mount Fuji. I'm exhausted already!

The prompt: “Create a 7-day itinerary for a dream vacation in Japan, including must-visit destinations, unique experiences, and local culinary delights. Offer suggestions for accommodations and transportation options to make the trip planning process easier.”

Sign up to get the BEST of Tom’s Guide direct to your inbox.

Upgrade your life with a daily dose of the biggest tech news, lifestyle hacks and our curated analysis. Be the first to know about cutting-edge gadgets and the hottest deals.

Remember with AI chatbots you don't have to just rely on a single prompt. You can follow up with requests such as, lets keep it all in Tokyo for the full seven days, now refine the itinerary, or suggest alternative hotels. You can adapt this prompt with the country of your choice, or even make it a city break.

2. Writing a love song

Some weeks with Prompt_Jitsu I'll try to create a theme, this week the theme is cool things to try in Copilot, with no particular link. Although maybe you could use this prompt to create a love song to sing to someone you met in Japan.

The prompt: “Compose a heartfelt love song that captures the essence of a long-distance relationship. Include lyrics that express the challenges, yearning, and unwavering commitment of two people separated by distance but united by their love.”

This prompt will give you a set of lyrics for a love song if Suno is disabled in the plugins menu. If you have Suno enabled it will create a full song with vocals.

In my cases included the following line in the chorus: "Cause you're the sound of my heart, the beat in my chest. Every time you're near, I can't catch my breath." 

3. Promotional poster

You've got your song, now you need somewhere to perform the track. This next prompt will use Designer, the DALL-E powered image generator in Copilot to generate a poster for a fictional music festival.

The prompt: “Design a series of eye-catching promotional posters for a fictional music festival featuring an eclectic mix of genres and artists. Include elements that reflect the festival's theme, location, and overall vibe, and create designs that would appeal to a wide audience.”

You can adapt the prompt to reflect a real world scenario or event. Adjust the prompt to replace fictional music festival with something like "flyer for ten year old's birthday party" or even "garage sale". You can also edit the image in Designer to change the resolution or adjust any individual feature.

4. Creating a business plan

You've been to Japan, written a killer love song and created a poster for a fake music festival. Why not now develop a business plan for a clothing line to sell at the fake music festival? Lets make it eco-friendly.

The prompt: “Develop a detailed business plan for a sustainable, eco-friendly clothing line that uses innovative materials and production methods. Include information on target market, product offerings, pricing strategy, marketing approach, and financial projections.”

In my case it offered up a target market description, product offerings, pricing strategy and financial projections. It was just an overview but you can use follow up prompts. It suggests some such as "what are some innovative materials I can use?" and "How do I find ethical manufacturers for my clothing line?".

I also asked Copilot to create an image of one of the products we might sell.

5. Mental health awareness

We've travelled the world, expressed our undying love through song, designed a poster for a music festival and made a business plan to sell eco-friendly clothing. Now its time to put something back into society with a speech.

The prompt: “Write a persuasive speech advocating for the importance of mental health awareness and support in the workplace. Include statistics, personal anecdotes, and practical strategies for creating a more supportive and inclusive work environment.”

In the first response it gave me a rough outline and structure, including bullet points and links for quotes and statistics — so I had to follow up with a request for the full speech.

You can follow up with prompts like "make it funnier, or add some examples using quotes from the web or famous people.". You could even put the speech into a tool like ElevenLabs and have AI read it for you. In the example I used my own voice clone.

6. Social media posts

No business can succeed without social media promotion. This next prompt will generate a series of prompts to promote a pet grooming business, and not just normal promo posts but tips, images and more.

The prompt: “Generate a series of fun and engaging social media posts for a pet grooming business, including tips for pet owners, behind-the-scenes glimpses of the grooming process, and adorable images of freshly groomed pets.”

It gave me five posts and even generated images to use in the posts requiring pictures. It suggested starting with tips for shiny fur, followed by a behind the scenes on a grooming session and at the end a meet the team.

7. Designing a garden

After all that hard work why not design your dream garden, or at least use Copilot to give you a step-by-step guide to laying a raised garden bed.

The prompt: “Create a step-by-step guide for building a raised garden bed, including materials needed, tools required, and detailed instructions for each stage of the process. Offer tips for selecting the right location, choosing plants, and maintaining the garden over time.”

It effectively gave me a recipe with materials, tools and instructions. It also suggests location ideas, ideal plants and advice on maintaining the garden.

You could follow the prompt with specific requests around style, seasonality or even replace raised bed with herb garden or rockery.

OpenAI Unveils A.I. Technology That Recreates Human Voices

The start-up is sharing the technology, Voice Engine, with a small group of early testers as it tries to understand the potential dangers.

• Share full article

By Cade Metz

Reporting from San Francisco

First, OpenAI offered a tool that allowed people to create digital images simply by describing what they wanted to see. Then, it built similar technology that generated full-motion video like something from a Hollywood movie.

Now, it has unveiled technology that can recreate someone’s voice.

The high-profile A.I. start-up said on Friday that a small group of businesses was testing a new OpenAI system, Voice Engine, that can recreate a person’s voice from a 15-second recording. If you upload a recording of yourself and a paragraph of text, it can read the text using a synthetic voice that sounds like yours.

The text does not have to be in your native language. If you are an English speaker, for example, it can recreate your voice in Spanish, French, Chinese or many other languages.

OpenAI is not sharing the technology more widely because it is still trying to understand its potential dangers. Like image and video generators, a voice generator could help spread disinformation across social media. It could also allow criminals to impersonate people online or during phone calls.

The company said it was particularly worried that this kind of technology could be used to break voice authenticators that control access to online banking accounts and other personal applications.

“This is a sensitive thing, and it is important to get it right,” an OpenAI product manager, Jeff Harris, said in an interview.

The company is exploring ways of watermarking synthetic voices or adding controls that prevent people from using the technology with the voices of politicians or other prominent figures.

Last month, OpenAI took a similar approach when it unveiled its video generator, Sora. It showed off the technology but did not publicly release it.

OpenAI is among the many companies that have developed a new breed of A.I. technology that can quickly and easily generate synthetic voices. They include tech giants like Google as well as start-ups like the New York-based ElevenLabs. (The New York Times has sued OpenAI and its partner, Microsoft, on claims of copyright infringement involving artificial intelligence systems that generate text.)

Businesses can use these technologies to generate audiobooks, give voice to online chatbots or even build an automated radio station DJ. Since last year, OpenAI has used its technology to power a version of ChatGPT that speaks . And it has long offered businesses an array of voices that can be used for similar applications. All of them were built from clips provided by voice actors.

But the company has not yet offered a public tool that would allow individuals and businesses to recreate voices from a short clip as Voice Engine does. The ability to recreate any voice in this way, Mr. Harris said, is what makes the technology dangerous. The technology could be particularly dangerous in an election year, he said.

In January, New Hampshire residents received robocall messages that dissuaded them from voting in the state primary in a voice that was most likely artificially generated to sound like President Biden . The Federal Communications Commission later outlawed such calls .

Mr. Harris said OpenAI had no immediate plans to make money from the technology. He said the tool could be particularly useful to people who lost their voices through illness or accident.

He demonstrated how the technology had been used to recreate a woman’s voice after brain cancer damaged it. She could now speak, he said, after providing a brief recording of a presentation she had once made as a high schooler.

News  and Analysis

U.S. clinics are starting to offer patients a new service: having their mammograms read not just by a radiologist, but also by an A.I. model .

OpenAI unveiled Voice Engine , an A.I. technology that can recreate a person’s voice from a 15-second recording.

Amazon said it had added $2.75 billion to its investment in Anthropic , an A.I. start-up that competes with companies like OpenAI and Google.

The Age of A.I.

A.I. is peering into restaurant garbage pails  and crunching grocery-store data to try to figure out how to send less uneaten food into dumpsters.

David Autor, an M.I.T. economist and tech skeptic, argues that A.I. is fundamentally different  from past waves of computerization.

Economists doubt that A.I. is already visible in productivity data . Big companies, however, talk often about adopting it to improve efficiency.

The Caribbean island Anguilla made $32 million last year, more than 10& of its G.D.P., from companies registering web addresses that end in .ai .

When it comes to the A.I. that powers chatbots, China trails the United States. But when it comes to producing the scientists behind a new generation of humanoid technologies, China is pulling ahead .

OpenAI built a voice cloning tool, but you can’t use it… yet

As deepfakes proliferate , OpenAI is refining the tech used to clone voices — but the company insists it’s doing so responsibly.

Today marks the preview debut of OpenAI’s Voice Engine , an expansion of the company’s existing text-to-speech API . Under development for about two years, Voice Engine allows users to upload any 15-second voice sample to generate a synthetic copy of that voice. But there’s no date for public availability yet, giving the company time to respond to how the model is used and abused.

“We want to make sure that everyone feels good about how it’s being deployed — that we understand the landscape of where this tech is dangerous and we have mitigations in place for that,” Jeff Harris, a member of the product staff at OpenAI, told TechCrunch in an interview.

Training the model

The generative AI model powering Voice Engine has been hiding in plain sight for some time, Harris said.

The same model underpins the voice and “read aloud” capabilities in ChatGPT , OpenAI’s AI-powered chatbot, as well as the preset voices available in OpenAI’s text-to-speech API. And Spotify’s been using it since early September to dub podcasts for high-profile hosts like Lex Fridman in different languages.

I asked Harris where the model’s training data came from — a bit of a touchy subject. He would only say that the Voice Engine model was trained on a mix of licensed and publicly available data.

Models like the one powering Voice Engine are trained on an enormous number of examples — in this case, speech recordings — usually sourced from public sites and data sets around the web. Many generative AI vendors see training data as a competitive advantage and thus keep it and info pertaining to it close to the chest. But training data details are also a potential source of IP-related lawsuits, another disincentive to reveal much.

OpenAI is already being   sued over allegations the company violated IP law by training its AI on copyrighted content, including photos, artwork, code, articles and e-books, without providing the creators or owners credit or pay.

OpenAI has licensing agreements in place with some content providers, like Shutterstock and the news publisher Axel Springer , and allows webmasters to block its web crawler from scraping their site for training data. OpenAI also lets artists “opt out” of and remove their work from the data sets that the company uses to train its image-generating models, including its latest DALL-E 3 .

But OpenAI offers no such opt-out scheme for its other products. And in a recent statement to the U.K.’s House of Lords, OpenAI suggested that it’s “impossible” to create useful AI models without copyrighted material, asserting that fair use — the legal doctrine that allows for the use of copyrighted works to make a secondary creation as long as it’s transformative — shields it where it concerns model training.

Synthesizing voice

Surprisingly, Voice Engine isn’t trained or fine-tuned on user data. That’s owing in part to the ephemeral way in which the model — a combination of a diffusion process and transformer — generates speech.

“We take a small audio sample and text and generate realistic speech that matches the original speaker,” said Harris. “The audio that’s used is dropped after the request is complete.”

As he explained it, the model is simultaneously analyzing the speech data it pulls from and the text data meant to be read aloud, generating a matching voice without having to build a custom model per speaker.

It’s not novel tech. A number of startups have delivered voice cloning products for years, from ElevenLabs to Replica Studios to Papercup to Deepdub to Respeecher . So have Big Tech incumbents such as Amazon, Google and Microsoft — the last of which is a major OpenAI’s investor  incidentally.

Harris claimed that OpenAI’s approach delivers overall higher-quality speech.

We also know it will be priced aggressively. Although OpenAI removed Voice Engine’s pricing from the marketing materials it published today, in documents viewed by TechCrunch, Voice Engine is listed as costing $15 per one million characters, or ~162,500 words. That would fit Dickens’ “Oliver Twist” with a little room to spare. (An “HD” quality option costs twice that, but confusingly, an OpenAI spokesperson told TechCrunch that there’s no difference between HD and non-HD voices. Make of that what you will.)

That translates to around 18 hours of audio, making the price somewhat south of $1 per hour. That’s indeed cheaper than what one of the more popular rival vendors, ElevenLabs, charges — $11 for 100,000 characters per month. But it does come at the expense of some customization.

Voice Engine doesn’t offer controls to adjust the tone, pitch or cadence of a voice. In fact, it doesn’t offer any fine-tuning knobs or dials at the moment, although Harris notes that any expressiveness in the 15-second voice sample will carry on through subsequent generations (for example, if you speak in an excited tone, the resulting synthetic voice will sound consistently excited). We’ll see how the quality of the reading compares with other models when they can be compared directly.

Voice talent as commodity

Voice actor salaries on ZipRecruiter range from $12 to $79 per hour — a lot more expensive than Voice Engine, even on the low end (actors with agents will command a much higher price per project). Were it to catch on, OpenAI’s tool could commoditize voice work. So, where does that leave actors?

The talent industry wouldn’t be caught unawares, exactly — it’s been grappling with the existential threat of generative AI for some time. Voice actors are increasingly being asked to sign away rights to their voices so that clients can use AI to generate synthetic versions that could eventually replace them. Voice work — particularly cheap, entry-level work — is at risk of being eliminated in favor of AI-generated speech.

Now, some AI voice platforms are trying to strike a balance.

Replica Studios last year signed a somewhat contentious deal with SAG-AFTRA to create and license copies of the media artist union members’ voices. The organizations said that the arrangement established fair and ethical terms and conditions to ensure performer consent while negotiating terms for uses of synthetic voices in new works, including video games.

The writers’ strike is over; here’s how AI negotiations shook out

ElevenLabs, meanwhile, hosts a marketplace for synthetic voices that allows users to create a voice, verify and share it publicly. When others use a voice, the original creators receive compensation — a set dollar amount per 1,000 characters.

OpenAI will establish no such labor union deals or marketplaces, at least not in the near term, and requires only that users obtain “explicit consent” from the people whose voices are cloned, make “clear disclosures” indicating which voices are AI-generated and agree not to use the voices of minors, deceased people or political figures in their generations.

“How this intersects with the voice actor economy is something that we’re watching closely and really curious about,” Harris said. “I think that there’s going to be a lot of opportunity to sort of scale your reach as a voice actor through this kind of technology. But this is all stuff that we’re going to learn as people actually deploy and play with the tech a little bit.”

Ethics and deepfakes

Voice cloning apps can be — and have been — abused in ways that go well beyond threatening the livelihoods of actors.

The infamous message board 4chan, known for its conspiratorial content,  used ElevenLabs’ platform to share hateful messages mimicking celebrities like Emma Watson. The Verge’s James Vincent was able to tap AI tools to maliciously, quickly clone voices, generating samples containing everything from violent threats to racist and transphobic remarks. And over at Vice, reporter Joseph Cox documented generating a voice clone convincing enough to fool a bank’s authentication system.

There are fears bad actors will attempt to sway elections with voice cloning. And they’re not unfounded: In January, a phone campaign employed a deepfaked President Biden to deter New Hampshire citizens from voting — prompting the FCC to move to make future such campaigns illegal.

FCC officially declares AI-voiced robocalls illegal

So aside from banning deepfakes at the policy level, what steps is OpenAI taking, if any, to prevent Voice Engine from being misused? Harris mentioned a few.

First, Voice Engine is only being made available to an exceptionally small group of developers — around 10 — to start. OpenAI is prioritizing use cases that are “low risk” and “socially beneficial,” Harris says, like those in healthcare and accessibility, in addition to experimenting with “responsible” synthetic media.

A few early Voice Engine adopters include Age of Learning, an edtech company that’s using the tool to generate voice-overs from previously cast actors, and HeyGen, a storytelling app leveraging Voice Engine for translation. Livox and Lifespan are using Voice Engine to create voices for people with speech impairments and disabilities, and Dimagi is building a Voice Engine-based tool to give feedback to health workers in their primary languages.

Here’s generated voices from Lifespan:

And here’s one from Livox:

Second, clones created with Voice Engine are watermarked using a technique OpenAI developed that embeds inaudible identifiers in recordings. (Other vendors including Resemble AI and Microsoft employ similar watermarks.) Harris didn’t promise that there aren’t ways to circumvent the watermark, but described it as “tamper resistant.”

“If there’s an audio clip out there, it’s really easy for us to look at that clip and determine that it was generated by our system and the developer that actually did that generation,” Harris said. “So far, it isn’t open sourced — we have it internally for now. We’re curious about making it publicly available, but obviously, that comes with added risks in terms of exposure and breaking it.”

OpenAI launches a red teaming network to make its models more robust

Third, OpenAI plans to provide members of its red teaming network , a contracted group of experts that help inform the company’s AI model risk assessment and mitigation strategies, access to Voice Engine to suss out malicious uses.

Some experts argue that AI red teaming isn’t exhaustive enough and that it’s incumbent on vendors to develop tools to defend against harms that their AI might cause. OpenAI isn’t going quite that far with Voice Engine — but Harris asserts that the company’s “top principle” is releasing the technology safely.

General release

Depending on how the preview goes and the public reception to Voice Engine, OpenAI might release the tool to its wider developer base, but at present, the company is reluctant to commit to anything concrete.

Harris did give a sneak peek at Voice Engine’s roadmap, though, revealing that OpenAI is testing a security mechanism that has users read randomly generated text as proof that they’re present and aware of how their voice is being used. This could give OpenAI the confidence it needs to bring Voice Engine to more people, Harris said — or it might just be the beginning.

“What’s going to keep pushing us forward in terms of the actual voice matching technology is really going to depend on what we learn from the pilot, the safety issues that are uncovered and the mitigations that we have in place,” he said. “We don’t want people to be confused between artificial voices and actual human voices.”

And on that last point we can agree.
