Frequently asked questions

What is ai voice cloning.

AI voice cloning is a technology that creates synthetic copies of human voices. It analyzes audio recordings to mimic the tone, pitch, and characteristics of a person's voice. At ElevenLabs, we use Voice Cloning for personalized voice solutions, enhancing content creation and engagement. We offer two types of voice cloning: Instant Voice Cloning and Professional Voice Cloning. Instant Voice Cloning is a quick and easy way to clone your voice. In both cases they work best with clean audio files containing a single speaker with no background noise, music or other effects. It works best with a sample of at least 1 minute of audio. Professional Voice Cloning is a more advanced process that requires a minimum of 30 minutes of audio. The result is a voice that is virtually indistinguishable from the real thing.

How do I create AI voices?

Get started for free by creating an account. You can then instantly create AI voice audio with our Speech Synthesis tool. To create your own AI voice characters, you can use VoiceLab for instant cloning or creating new characters from scratch.

How does voice cloning work?

Voice cloning works by first capturing a person's voice through recordings, which serve as a learning material for the AI. During the analysis phase, the AI examines these voice samples to identify distinctive characteristics like intonation and accent. It utilizes advanced machine learning methods, primarily neural networks, to deeply understand and mimic the nuances of the voice. The AI, once adequately trained, can then synthesize speech that closely resembles the original voice, enabling it to articulate phrases or sentences that were never recorded. This technology has significant applications, ranging from enhancing personalized digital experiences to aiding those with speech impairments, but it also necessitates cautious handling to avoid unethical uses.

How do I get the best voice cloning quality?

We recommend using Professional Voice Cloning to create the perfect voice clone. After uploading a minimum of 30 minutes of audio, and verifying that it is your own voice, you will be notified once your voice clone is ready (~2-6 hours). Otherwise, you can use Instant Voice Cloning to create a voice clone immediately. This will work best with no background noise, and a sample of at least 1 minute.

What languages do you support?

We support: English Japanese, Chinese, German, Hindi, French, Korean, Portuguese, Italian, Spanish, Indonesian, Dutch, Turkish, Filipino, Polish, Swedish, Bulgarian, Romanian, Arabic, Czech, Greek, Finnish, Croatian, Malay, Slovak, Danish, Tamil & Ukrainian. New languages are to be added sequentially.

Yes, as long as you have their consent. For Professional Voice Cloning, we have integrated security measures to make sure you can only clone your own voice. Unless you share it, your voice belongs and is available only to you.

Take the entertainment industry, for instance. AI voice cloning has revolutionized dubbing, allowing for seamless voice replication of iconic characters and preserving legacies in the industry. Creators love it, too it’s turbocharging content creation with a lightning-fast solution.

And it’s not just about movies and shows. Think about accessibility. People who have lost their voice now have a way to create a clone that closely resembles their natural speech patterns, making communication a lot smoother and more personalized. 

Customer service is getting a facelift, too. AI voice cloning makes interactions more personal, which is a win for everyone involved. 

In short, voice cloning technology is pushing the boundaries of what’s possible, making our voices not just heard but celebrated in incredible ways.

How Does AI Voice Cloning Work?

You must be wondering: how does AI pull off such convincing voice cloning feats? It’s a blend of technological prowess and data-driven finesse that powers this remarkable capability.

At the heart of AI voice cloning lies a substantial reservoir of voice data recordings that capture the essence of an individual’s voice. These recordings serve as the foundation, allowing the AI model to dissect and comprehend the intricacies of speech, from unique tones to subtle nuances that define a voice.

This technology leans heavily on sophisticated algorithms, particularly deep neural networks. These algorithms break down the voice recordings into smaller components, analyzing patterns and features crucial for replication. Through ‘generative models,’ the AI system learns to generate new speech segments by predicting sequences based on these learned patterns, honing its ability to produce remarkably authentic speech.

What’s truly impressive is the progress in real-time voice cloning. Now, the AI can create a voice clone that closely mimics a specific voice instantly without extensive preprocessing. This advancement opens doors to live applications from voice conversion in real time to instant speech synthesis for various purposes.

And here’s the kicker while some AI voice cloning services come at a cost, several platforms offer AI voice cloning free. These leverage open-source frameworks and models, ensuring accessibility to this remarkable technology without financial barriers.

In essence, AI voice cloning is a blend of cutting-edge algorithms, vast datasets, and continuous learning, resulting in the ability to replicate voices with incredible precision, unlocking a multitude of applications across diverse fields.

Key Applications of AI Voice Cloning

The ability to craft personalized voice models elevates the level of interaction, making voice assistants more intuitive and engaging. Custom voice cloning bridges the gap between technology and personal preference, offering a sense of ownership over one’s digital interactions.

Content Creation

For creators, AI voice cloning technology is a boon. Content producers can whip up top-notch voiceovers in their own or favorite celebrity’s voice in minutes. These tools not only expedite the content creation process but also ensure a consistent tone and style across various mediums. It’s a game-changer for podcasters, authors, and filmmakers, enabling them to produce studio-quality content faster without compromising quality.

Dubbing and Localization

Imagine a streamlined and automated dubbing process that is both swift and cost-effective while also reducing the need for extensive actor engagement.

That is precisely what voice cloning helps achieve. You can also seamlessly adapt the content to multiple languages. That means breaking linguistic barriers and fostering global connections. Furthermore, the ability to tailor accents enables precise localization, ensuring that content resonates authentically with diverse audiences.

Thanks to accessible voice cloning apps and online platforms, it has become easier to clone voice with AI. These user-friendly interfaces and tools make exploring and leveraging AI voice cloning’s potential a smoother journey for everyone.

What Can You Do With Murf Voice Cloning Software?

With Murf’s AI voice cloning technology, you can now clone the voice of voice actors of your choice anytime from anywhere (provided you have the legal rights to do so). 

Voice cloning for E-learning

The global e-learning market was expected to reach a staggering total market value of $325 billion by 2025 before the pandemic. And then, the COVID-19 pandemic hit the world, and e-learning became one of the primary sources of education worldwide. While e-learning makes it possible to reach a large audience in one go, it becomes difficult for educators to take classes online. Asynchronous education can be a solution where the educator can make videos and make them online. So basically, educators now have to become content creators -they are not trained to become podcasters or YouTubers and read long scripts from the course material. 

Custom voices here come as a natural solution. Educators have to create recorded speech in their voice, and then Murf’s AI technology can clone the voice at the backend and create cloned voice Avatars of the educators.

Speech to Speech Voice Cloning: A Comprehensive Guide

Table of contents.

Voice cloning, a facet of speech synthesis and artificial intelligence (AI), has gained immense traction in the modern tech landscape. It’s a process involving deep learning and neural networks to create a synthetic version of a person’s voice. With the rise in AI technology, understanding voice cloning becomes essential for content creators, voice actors, and the public. This article explores various aspects of voice cloning , including software, differences, applications, and more.

Is Voice Cloning the Same as TTS?

Voice cloning and text-to-speech (TTS) may seem similar but differ in application and algorithms. TTS translates text into speech using predefined voice models, while voice cloning creates a unique voice, replicating a target voice through deep learning.

How to Clone Someone’s Voice?

Voice cloning involves the following steps:

• Collecting Voice Samples : Requires a substantial amount of audio content from the original voice.
• Preprocessing : Enhancing the quality of audio files and alignment with text.
• Training a Model : Utilizing neural networks, machine learning, and AI technology to create a voice model.
• Synthesizing the Voice : Generating a high-quality, artificial voice that resembles the target voice.

Software for Voice Cloning

Here are the top 8 voice cloning software or apps:

• iSpeech : AI voice cloning technology for custom voice creation. Pricing available on the website.

Voice Cloning Vs. Voice Modulation

Voice cloning reproduces a unique voice, while voice modulation alters an existing voice without replicating a specific person’s voice.

Voice Cloning & Speech-to-Text Vs. Speech-to-Speech Cloning

Speech-to-text transcribes voice into text, while speech-to-speech voice cloning involves translating one voice to another, retaining the spoken content.

Changing Voice & Voice Changers for Android

Various apps enable real-time voice changes, like Voicemod for Android. Voice cloning technology adds more personalized touch.

Can You Clone a Voice Without the Person’s Voice?

Cloning a specific voice requires original voice samples. Without these, generic synthetic voices can be created but not a unique voice replica.

Making Voice Sound Different

Voice modulation, dubbing, and voice cloning software can be used to mimic or alter a voice, suitable for game development, social media, and more.

Pros & Cons of Voice Cloning

• Pros : Accessibility in content, personalized e-learning, AI-generated voices for audiobooks, podcasts.
• Cons : Ethical concerns, potential misuse (deepfake), loss of work for voice actors.

How to Use Voice Cloning?

Voice cloning can be applied in various fields:

• Audiobooks & Podcasts : Utilizing synthetic voices for narration.
• E-learning : Custom voice for immersive learning experiences.
• Media & Entertainment : Dubbing, voiceovers, unique character voices.

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.

How to Protect Yourself (and Your Loved Ones) From AI Scam Calls

You answer a random call from a family member, and they breathlessly explain how there’s been a horrible car accident. They need you to send money right now, or they’ll go to jail. You can hear the desperation in their voice as they plead for an immediate cash transfer. While it sure sounds like them, and the call came from their number, you feel like something’s off. So, you decide to hang up and call them right back. When your family member picks up your call, they say there hasn’t been a car crash, and that they have no idea what you’re talking about.

Congratulations, you just successfully avoided an artificial intelligence scam call.

As generative AI tools get more capable, it is becoming easier and cheaper for scammers to create fake—but convincing—audio of people’s voices. These AI voice clones are trained on existing audio clips of human speech, and can be adjusted to imitate almost anyone . The latest models can even speak in numerous languages. OpenAI, the maker of ChatGPT , recently announced a new text-to-speech model that could further improve voice cloning and make it more widely accessible.

Of course, bad actors are using these AI cloning tools to trick victims into thinking they are speaking to a loved one over the phone, even though they’re talking to a computer. While the threat of AI-powered scams can be frightening, you can stay safe by keeping these expert tips in mind the next time you receive an urgent, unexpected call.

Remember That AI Audio Is Hard to Detect

It’s not just OpenAI; many tech startups are working on replicating near perfect-sounding human speech, and the recent progress is rapid. “If it were a few months ago, we would have given you tips on what to look for, like pregnant pauses or showing some kind of latency,” says Ben Colman, cofounder and CEO of Reality Defender . Like many aspects of generative AI over the past year, AI audio is now a more convincing imitation of the real thing. Any safety strategies that rely on you audibly detecting weird quirks over the phone are outdated.

Hang Up and Call Back

Security experts warn that it’s quite easy for scammers to make it appear as if the call were coming from a legitimate phone number. “A lot of times scammers will spoof the number that they're calling you from, make it look like it's calling you from that government agency or the bank,” says Michael Jabbara, global head of fraud services at Visa . “You have to be proactive.” Whether it’s from your bank or from a loved one, any time you receive a call asking for money or personal information, go ahead and ask to call them back. Look up the number online or in your contacts, and initiate a follow-up conversation. You can also try sending them a message through a different, verified line of communication like video chat or email.

Create a Secret Safe Word

A popular security tip that multiple sources suggested was to craft a safe word that only you and your loved ones know about, and which you can ask for over the phone. “You can even prenegotiate with your loved ones a word or a phrase that they could use in order to prove who they really are, if in a duress situation,” says Steve Grobman, chief technology officer at McAfee . Although calling back or verifying via another means of communication is best, a safe word can be especially helpful for young ones or elderly relatives who may be difficult to contact otherwise.

Or Just Ask What They Had for Dinner

What if you don’t have a safe word decided on and are trying to suss out whether a distressing call is real? Pause for a second and ask a personal question. “It could even be as simple as asking a question that only a loved one would know the answer to,” says Grobman. “It could be, ‘Hey, I want to make sure this is really you. Can you remind me what we had for dinner last night?’” Make sure the question is specific enough that a scammer couldn’t answer correctly with an educated guess.

Understand Any Voice Can Be Mimicked

Deepfake audio clones aren’t just reserved for celebrities and politicians, like the calls in New Hampshire that used AI tools to sound like Joe Biden and to discourage people from going to the polls. “One misunderstanding is, ‘It cannot happen to me. No one can clone my voice,’” says Rahul Sood, chief product officer at Pindrop , a security company that discovered the likely origins of the AI Biden audio . “What people don’t realize is that with as little as five to 10 seconds of your voice, on a TikTok you might have created or a YouTube video from your professional life, that content can be easily used to create your clone.” Using AI tools, the outgoing voicemail message on your smartphone might even be enough to replicate your voice.

Don’t Give in to Emotional Appeals

Whether it’s a pig butchering scam or an AI phone call, experienced scammers are able to build your trust in them, create a sense of urgency, and find your weak points. “Be wary of any engagement where you’re experiencing a heightened sense of emotion, because the best scammers aren’t necessarily the most adept technical hackers,” says Jabbara. “But they have a really good understanding of human behavior.” If you take a moment to reflect on a situation and refrain from acting on impulse, that could be the moment you avoid getting scammed.

OpenAI claims its software can clone your voice from 15 seconds of you talking

Super lab loves to big up things it says it couldn't possibly let loose on the world for now.

OpenAI's latest trick needs just 15 seconds of audio of someone speaking to clone that person's voice – but don't worry, no need to look behind the curtain, the biz wants everyone to know it's not going to release this Voice Engine until it can be sure the potential for mischief has been managed. 

Described as being a "small model" that uses a 15-second clip and a text prompt to generate natural-sounding speech resembling the original vocalist, OpenAI said it's already been testing the system with several "trusted partners." It has provided purported samples of Voice Engine's capabilities in marketing bumf emitted at the end of last month. 

According to OpenAI, Voice Engine can be used to do things like provide reading assistance, translate content, support non-verbal people, help medical patients who've lost their voices regain the ability to speak in their own voice and expand access to services in remote settings. All those use cases are demoed and have been part of the work OpenAI has been doing with early partners. 

News of the existence of Voice Engine, which OpenAI said was developed in late 2022 to serve as the tech behind ChatGPT Voice, Read Aloud, and its text-to-speech API, comes as concerns over voice cloning have reached a fever pitch of late.

One of the most headline-grabbing voice cloning stories of the year came from the New Hampshire presidential primary in the US, during which AI-generated robocalls of President Biden went out urging voters not to participate in the day's voting. 

Since then the FCC has formally declared AI-generated robocalls to be illegal, and the FTC has issued a $25,000 bounty to solicit ideas on how to combat the growing threat of AI voice cloning. 

Most recently, former US Secretary of State, senator and First Lady Hillary Clinton has warned that the 2024 election cycle will be " ground zero " for AI-driven election manipulation. So why come forward with another potentially trust-shattering technology in the midst of such a debate? 

• OpenAI tweaks its fine print, removes explicit ban on 'military and warfare' use
• Microsoft seeks patent for tech to put words into your mouth
• Daughter of George Carlin horrified someone cloned her dad with AI for hour special
• You may have heard about AI defeating voice authentication. This research kinda proves it

"We hope to start a dialogue on the responsible deployment of synthetic voices, and how society can adapt to these new capabilities," OpenAI said.

"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," the lab added. "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." 

To assist in preventing voice-based fraud, OpenAI said it is encouraging others to phase out voice-based authentication, explore what can be done to protect individuals against such capabilities, and accelerate tech to track the origin of audiovisual content "so it's always clear when you're interacting with a real person or with an AI." 

That said, OpenAI also seems to accept that, even if it doesn't end up deploying Voice Engine, someone else will likely create and release a similar product - and it might not be someone as trustworthy as them, you know. 

"It's important that people around the world understand where this technology is headed, whether we ultimately deploy it widely ourselves or not," OpenAI said. 

So consider this an oh-so friendly warning that, even if OpenAI isn't the reason, you can't trust everything you hear on the internet nowadays. ®

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:

https://techcrunch.com/wp-content/uploads/2024/03/livox_generation_english.mp3

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 deems its voice cloning tool too risky for general release

Delaying the Voice Engine technology rollout minimises the potential for misinformation in an important global election year

A new tool from OpenAI that can generate a convincing clone of anyone’s voice using just 15 seconds of recorded audio has been deemed too risky for general release, as the AI lab seeks to minimise the threat of damaging misinformation in a global year of elections.

Voice Engine was first developed in 2022 and an initial version was used for the text-to-speech feature built into ChatGPT , the organisation’s leading AI tool. But its power has never been revealed publicly, in part because of the “cautious and informed” approach that OpenAI is taking to release it more widely.

“We hope to start a dialogue on the responsible deployment of synthetic voices, and how society can adapt to these new capabilities,” OpenAI said in an unsigned blogpost. “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 its post the company shared examples of real-world uses of the technology from various partners who were given access to it to build into their own apps and products.

Education technology firm Age of Learning uses it to generate scripted voiceovers, while “AI visual storytelling” app HeyGen offers users the ability to generate translations of recorded content in a way that is fluent but preserves the accent and voice of the original speaker. For example, generating English with an audio sample from a French speaker produces speech with a French accent.

Notably, researchers at the Norman Prince Neurosciences Institute in Rhode Island used a poor-quality 15-second clip of a young woman giving a presentation at a school project to “restore the voice” that she had lost due to a vascular brain tumour.

“We are choosing to preview but not widely release this technology at this time,” OpenAI said, in order “to bolster societal resilience against the challenges brought by ever more convincing generative models”. In the immediate future, it said: “We encourage steps like phasing out voice-based authentication as a security measure for accessing bank accounts and other sensitive information.”

OpenAI also called for the exploration of “policies to protect the use of individuals’ voices in AI” and “educating the public in understanding the capabilities and limitations of AI technologies, including the possibility of deceptive AI content”.

Voice Engine generations are watermarked, OpenAI said, which allows the organisation to trace the origin of any generated audio. Currently, it added, “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”.

But while OpenAI’s tool stands out for the technical simplicity and the tiny amount of original audio required to generate a convincing clone, competitors are already available to the public.

With just a “few minutes of audio”, companies such as ElevenLabs can generate a complete voice clone. To try to mitigate harms, the company has introduced a “no-go voices” safeguard, designed to detect and prevent the creation of voice clones “that mimic political candidates actively involved in presidential or prime ministerial elections, starting with those in the US and the UK”.

OpenAI debuts voice cloning tool, but deems it too risky for public release

ChatGPT creator says Voice Engine can replicate a person’s voice based on a 15-second audio sample.

OpenAI has unveiled a tool for cloning people’s voices but is holding back on its public release due to concerns about possible misuse in a key election year.

Voice Engine can replicate a person’s voice based on a 15-second audio sample, according to an OpenAI blog post demonstrating the tool.

Tens of thousands take part in antigovernment protests in israel, israeli military says it killed hezbollah commander, turkey’s opposition claims victory in major cities, the high cost of being a whistleblower in china.

But the ChatGPT creator is “taking a cautious and informed approach” to the technology and hopes to start a dialogue on “the responsible deployment of synthetic voices”, the company said in the blog post published on Friday.

“We recognize that generating speech that resembles people’s voices has serious risks, which are especially top of mind in an election year,” the San Francisco-based start-up said.

“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.”

OpenAI said it would make “a more informed decision” about deploying the technology at scale based on testing and public debate.

The company added that it believes the technology should only be rolled out with measures that ensure the “original speaker is knowingly adding their voice to the service” and prevent the “creation of voices that are too similar to prominent figures.”

The misuse of AI has emerged as a major concern ahead of elections this year in countries representing about half the world’s population.

Voters in more than 80 countries, including Mexico, South Africa and the United States are going to the polls in 2024 , which has been dubbed the biggest election year in history.

The influence of AI on voters has already come under scrutiny in several elections.

Pakistan’s jailed former Prime Minister Imran Khan used AI-generated speeches to appeal to supporters in the run-up to the country’s parliamentary elections in February.

In January, a political operative for the long-shot US presidential candidate Dean Phillips put out a robocall impersonating US President Joe Biden that urged voters not to cast their ballots in New Hampshire’s Democratic Party primary.

OpenAI said it had implemented several safety measures for its partners testing Voice Engine, “including watermarking to trace the origin of any audio generated by Voice Engine, as well as proactive monitoring of how it’s being used”.

adventures in speech synthesis —

Openai holds back wide release of voice-cloning tech due to misuse concerns, voice engine can clone voices with 15 seconds of audio, but openai is warning of potential harms..

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 also convincingly imitate existing voices using small samples of audio.

Along those lines, OpenAI just 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 yet. 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—we've covered 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 their 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 Sen. Sherrod Brown (D-Ohio), the chairman 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.
