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.

Frequently Asked Questions

Can someone else use descript’s overdub tts to clone my voice.

No. When creating an Overdub Voice, Descript users must positively affirm their identity and give Descript their express consent to train and generate a synthesized version of their voice.

Voice-training data that does not include this Voice ID cannot be used to create an Overdub Voice. In other words, unless you specifically consent to Overdub Voice creation, Descript will not create your Overdub Voice.

We verify this consent by authenticating the audio file uploaded against our training script to ensure that the voice recorded belongs to the person submitting it.

Is Descript Text-to-Speech free?

Overdub text-to-speech is free on all Descript accounts. Pro accounts get an unlimited Overdub vocabulary.

Is there a difference between Overdub generated with the Pro subscription vs. a Creator or Free subscription?

Yes. While you can create a custom Voice on Overdub with any subscription,  Free and Creator plans are limited to a list of the 1,000 most common vocabulary words. Any words that are not on that list will be replaced with "jibber" or "jabber." To avoid this gibberish and gain access to the full vocabulary list, you can upgrade to the Pro subscription.

How can I improve the quality of my text-to-speech voice?

TTS voice quality relies on a number of factors, such as the quality of your microphone, background noise, and room surfaces. Check out our article on Overdub Voice Quality Tips for tips on how you can assure the best possible recording.

OpenAI says it can clone a voice from just 15 seconds of audio

The technology is an expansion of the company's pre-existing text-to-speech api..

OpenAI just announced that it recently conducted a small-scale preview of a new tool called Voice Engine. This is a voice cloning technology that can mimic any speaker by analyzing a 15-second audio sample. The company says it generates “natural-sounding speech” with “emotive and realistic voices.”

The technology is based on the company’s pre-existing text-to-speech API and it has been in the works since 2022. OpenAI has already been using a version of the toolset to power the preset voices available in the current text-to-speech API and the Read Aloud feature. There are a bunch of samples on the company’s official blog and they sound eerily close to the real thing. I encourage you to give them a listen and imagine the possibilities, both good and bad.

OpenAI says they see this technology being useful for reading assistance, language translation and helping those who suffer from sudden or degenerative speech conditions. The company brought up a Brown University pilot program that helped a patient with speech impairment issues by creating a Voice Engine clone pulled from audio recorded for a school project.

Despite the potential benefits, bad actors would certainly abuse this technology to engage in some serious deepfake tomfoolery, which is already a problem . With this in mind, Voice Engine isn’t quite ready for prime time, as there are serious privacy concerns that must be met before a full rollout.

OpenAI acknowledges that this tech has “serious risks, which are especially top of mind in an election year.” The company says its incorporating feedback from “US and international partners from across government, media, entertainment, education, civil society and beyond” to ensure the product launches with a minimal amount of risk. All preview testers agreed to OpenAI’s usage policies, which ban the impersonation of another individual without consent or legal right.

Additionally, anybody using the tech will have to disclose to their audience that the voices are AI-generated. OpenAI implemented safety measures, like watermarking to trace the origin of any audio and “proactive monitoring” of how the system is being used. When the product officially rolls out there will be a “no-go voice list” that detects and prevents AI-generated speakers that are too similar to prominent figures.

As for when that rollout will occur, OpenAI remains tight-lipped. TechCrunch uncovered some potential pricing data and it looks like it will undercut competitors in the space like ElevenLabs . Voice Engine could cost $15 per one million characters, which works out to around 162,500 words. This is about the length of Stephen King’s The Shining . It certainly sounds like a budget-friendly way to get an audiobook done. The marketing materials also make reference to an “HD” version that costs twice as much, but the company hasn’t detailed how that will work.

OpenAI has been making big moves this week. It just announced another partnership with its bestie Microsoft to build an AI-based supercomputer called “Stargate.” The project will reportedly cost a whopping $100 billion, according to The Information .

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.

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.

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 artificial intelligence is already visible in productivity data . Big companies, however, talk often about adopting it to improve efficiency.

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.

Gov. Bill Lee of Tennessee signed a bill  to prevent the use of A.I. to copy a performer’s voice. It is the first such measure in the United States.

French regulators said Google failed to notify news publishers  that it was using their articles to train its A.I. algorithms, part of a wider ruling against the company for its negotiating practices with media outlets.

Note: For some voices (Bane and Dalek, for example), you'll need to put on the correct "accent" for the voice transformation to work properly. Basically, try to make your voice sound like the target voice, and the engine will add some effects to make it sound like the real thing. Another random tip: You'll need to talk relatively slowly if you're using any of the "echo-ey" voices, otherwise the echos will make it hard to understand.

You can use the generated audio clips for any purpose at all (commercial usage included). There's no need to credit voicechanger.io if you don't want to.

OpenAI Can Re-Create Human Voices—but Won’t Release the Tech Yet

Voice synthesis has come a long way since 1978’s Speak & Spell toy, which once wowed people with its state-of-the-art ability to read words aloud using an electronic voice. Now, using deep-learning AI models , software can create not only realistic-sounding voices but can also convincingly imitate existing voices using small samples of audio.

Along those lines, OpenAI this week announced Voice Engine, a text-to-speech AI model for creating synthetic voices based on a 15-second segment of recorded audio. It has provided audio samples of the Voice Engine in action on its website .

Once a voice is cloned, a user can input text into the Voice Engine and get an AI-generated voice result. But OpenAI is not ready to widely release its technology. The company initially planned to launch a pilot program for developers to sign up for the Voice Engine API earlier this month. But after more consideration about ethical implications, the company decided to scale back its ambitions for now.

“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,” the company writes. “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.”

Voice cloning tech in general is not particularly new—there have been several AI voice synthesis models since 2022, and the tech is active in the open source community with packages like OpenVoice and XTTSv2 . But the idea that OpenAI is inching toward letting anyone use its particular brand of voice tech is notable. And in some ways, the company's reticence to release it fully might be the bigger story.

OpenAI says that benefits of its voice technology include providing reading assistance through natural-sounding voices, enabling global reach for creators by translating content while preserving native accents, supporting non-verbal individuals with personalized speech options, and assisting patients in recovering their own voice after speech-impairing conditions.

But it also means that anyone with 15 seconds of someone's recorded voice could effectively clone it, and that has obvious implications for potential misuse. Even if OpenAI never widely releases its Voice Engine, the ability to clone voices has already caused trouble in society through phone scams where someone imitates a loved one's voice and election campaign robocalls featuring cloned voices from politicians like Joe Biden.

Also, researchers and reporters have shown that voice-cloning technology can be used to break into bank accounts that use voice authentication (such as Chase's Voice ID ), which prompted US senator Sherrod Brown of Ohio, the chair of the US Senate Committee on Banking, Housing, and Urban Affairs, to send a letter to the CEOs of several major banks in May 2023 to inquire about the security measures banks are taking to counteract AI-powered risks.

OpenAI recognizes that the tech might cause trouble if broadly released, so it's initially trying to work around those issues with a set of rules. It has been testing the technology with a set of select partner companies since last year. For example, video synthesis company HeyGen has been using the model to translate a speaker's voice into other languages while keeping the same vocal sound.

To use Voice Engine, each partner must agree to terms of use that prohibit "the impersonation of another individual or organization without consent or legal right." The terms also require that partners acquire informed consent from the people whose voices are being cloned, and they must also clearly disclose that the voices they produce are AI-generated. OpenAI is also baking a watermark into every voice sample that will assist in tracing the origin of any voice generated by its Voice Engine model.

So, as it stands now, OpenAI is showing off its technology, but the company is not yet ready to put itself on the line (yet) for the potential social chaos a broad release might cause. Instead, the company has re-calibrated its marketing approach to appear as if it is warning all of us about this already-existing technology in a responsible way.

"We are taking a cautious and informed approach to a broader release due to the potential for synthetic voice misuse," the company said in a statement. "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."

In line with its mission to cautiously roll out the tech, OpenAI has provided three recommendations for how society should change to accommodate its technology in its blog post . These steps include phasing out voice-based authentication for bank accounts, educating the public in understanding "the possibility of deceptive AI content," and accelerating the development of techniques that can track the origin of audio content, "so it's always clear when you're interacting with a real person or with an AI."

OpenAI also says that future voice-cloning tech should require verifying that the original speaker is "knowingly adding their voice to the service" and creating a list of voices that are forbidden to clone, such as those that are "too similar to prominent figures." That kind of screening tech may end up excluding anyone whose voice might naturally and accidentally sound too close to a celebrity or US president.

Tech Developed in 2022

According to the company, OpenAI developed its Voice Engine technology in late 2022, and many people have already been using a version of the technology with pre-defined (and not cloned) voices in two ways: The spoken conversation mode in the ChatGPT app released in September and OpenAI's text-to-speech API that debuted in November of last year.

With all the voice-cloning competition out there, OpenAI says that Voice Engine is notable for being a “small” AI model (how small, exactly, we do not know). But having been developed in 2022, it almost feels late to the party. And it may not be perfect in its cloning ability. Previous user-trained text-to-voice models like those from ElevenLabs and Microsoft have struggled with accents that fall outside their training dataset.

For now, Voice Engine remains a limited release to select partners.

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.

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.

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.

OpenAI Unveils Audio Feature That Read Texts, Clones Human Voices

The company is sharing early demos and use cases from a small-scale preview of the text-to-speech model, called voice engine, which it has shared with about 10 developers so far, a spokesperson said..

OpenAI decided against a wider rollout of the feature, which it briefed reporters on earlier this month.

OpenAI is sharing early results from a test for a feature that can read words aloud in a convincing human voice - highlighting a new frontier for artificial intelligence and raising the spectre of deepfake risks.

The company is sharing early demos and use cases from a small-scale preview of the text-to-speech model, called Voice Engine, which it has shared with about 10 developers so far, a spokesperson said. 

A spokesperson for OpenAI said the company decided to scale back the release after receiving feedback from stakeholders such as policymakers, industry experts, educators and creatives. The company had initially planned to release the tool to as many as 100 developers through an application process, according to the earlier press briefing.

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

Other AI technology has already been used to fake voices in some contexts. In January, a bogus but realistic-sounding phone call purporting to be from President Joe Biden encouraged people in New Hampshire not to vote in the primaries - an event that stoked AI fears ahead of critical global elections.

Unlike OpenAI's previous efforts at generating audio content, Voice Engine can create speech that sounds like individual people, complete with their specific cadence and intonations. All the software needs is 15 seconds of recorded audio of a person speaking to recreate their voice.

During a demonstration of the tool, Bloomberg listened to a clip of OpenAI Chief Executive Officer Sam Altman briefly explaining the technology in a voice that sounded indistinguishable from his actual speech, but was entirely AI-generated.

"If you have the right audio setup, it's basically a human-caliber voice," said Jeff Harris, a product lead at OpenAI. "It's a pretty impressive technical quality." However, Harris said, "There's obviously a lot of safety delicacy around the ability to really accurately mimic human speech."

One of OpenAI's current developer partners using the tool, the Norman Prince Neurosciences Institute at the not-for-profit health system Lifespan, is using technology to help patients recover their voice. For example, the tool was used to restore the voice of a young patient who lost her ability to speak clearly due to a brain tumor by replicating her speech from an earlier recording for a school project, the company blog post said.

OpenAI's custom speech model can also translate the audio it generates into different languages. That makes it useful for companies in the audio business, like Spotify Technology SA. Spotify has already used the technology in its own pilot program to translate the podcasts of popular hosts like Lex Fridman. OpenAI also touted other beneficial applications of the technology, such as creating a wider range of voices for educational content for children.

In the testing program, OpenAI is requiring its partners to agree to its usage policies, obtain consent from the original speaker before using their voice, and to disclose to listeners that the voices they're hearing are AI-generated. The company is also installing an inaudible audio watermark to allow it to distinguish whether a piece of audio was created by its tool.

Before deciding whether to release the feature more broadly, OpenAI said it's soliciting feedback from outside experts. "It's important that people around the world understand where this technology is headed, whether we ultimately deploy it widely ourselves or not," the company said in the blog post.

OpenAI also wrote that it hopes the preview of its software "motivates the need to bolster societal resilience" against the challenges brought about by more advanced AI technologies. For example, the company called on banks to phase out voice authentication as a security measure for accessing bank accounts and sensitive information. It's also seeking public education about deceptive AI content and more development of techniques for detecting whether audio content is real or AI-generated.
