Hear from Our Customers

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

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

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

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

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

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

Frequently Asked Questions

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

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

How does TTS work?

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

Top Five Use Cases of Text to Speech Software

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

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

TTS in Assistive Technology

Using TTS platforms, people facing such problems can convert text to speech and learn by listening on the go. Text to speech solutions also improves literacy and comprehension skills. When used in language education, they can make learning more engaging. For example, it's much easier and faster to apprehend a foreign language when listening to the live translation of written words with correct intonation and pronunciation than when reading. 

TTS in Translations

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

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

TTS in Customer Service

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

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

TTS in Automotive Industry

They can be used in in-car conversational systems for navigational prompts and map data, infotainment systems to read aloud information about the car, such as fuel level or tire pressure, and swap music and voice assistants to place phone calls, read messages, and more.

TTS in Healthcare

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

Why text to speech matters for businesses?

It's an exciting time to stake your claim in the realm of speech synthesis. There are a number of key industries where the text to speech technology has already succeeded in making a dent.

That said, by using text to speech in voice-activated chatbots, businesses can provide customers, especially the visually impaired, with a more immersive experience, thereby enriching the customer experience.

Global market penetration

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

Increases Web Presence

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

I love using VEED as the speech to subtitles transcription is the most accurate I've seen on the market. It has enabled me to edit my videos in just a few minutes and bring my video content to the next level

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.

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.

Across the board, users want a piece of the pie when it comes to AI. It’s hardly surprising that there has been an influx of creative ways to test its abilities in the form of generators. Whether it’s music makers like Suno or video creators such as Sora , there are now a multitude of ways to play around with these new technologies. The next iteration of these gadgets includes voice generators, which can assist with tasks such as text-to-speech and voice cloning.

What are AI voice generators and how do they work?

AI voice generator software transforms written text into voices that closely resemble human speech. It can be customized for various speech styles, ages, genders, and accents, and can also translate text into multiple languages. An increasing number of people are using this technology to narrate YouTube videos, podcasts, and video games. There have even been reports of it being used to narrate audiobooks.

These generators rely on deep learning algorithms, which are a branch of artificial intelligence that improves through analyzing large volumes of data. The way it works involves first training on a large dataset of voice recordings. Through this training, the algorithms learn to recognize speech patterns, such as intonation, rhythm, and accents, from these recordings. The quality and variety of the data used to train the generator influence how well it can create different and precise voices.

After the training phase, the AI uses text-to-speech (TTS) technology to convert written text into spoken words. This process starts with the AI breaking down the input text into its phonetic elements, and then synthesizing these components to construct complete words and sentences.

To make it more realistic, some sophisticated AI voice generators integrate Natural Language Processing (NLP) techniques. NLP enables the AI to grasp and process the subtleties of human language, allowing it to adjust its output for linguistic nuances such as sarcasm, questions, or excitement. This makes the synthesized speech sound more natural and human. It’s expected to improve as these technologies evolve.

What are the best AI voice generators?

Using the pangram – a sentence that contains all the letters of the alphabet – we tested out the different AI voice generators out there:

“The quick brown fox jumps over the lazy dog.”

ElevenLabs is one of the most notable firms in this area of AI. Its free online software provides users access to 27 different voice options, as well as the ability to translate into 29 different languages, including Chinese, Hindi, and Russian. The software is free and users are able to download on the free version. Users should be cautious when translating from English to other languages, as the translations are not always accurate and can significantly alter the intended meaning.

The maximum number of characters that can be generated in a single request on the platform is 2,500 for users who are not subscribed and 5,000 for those who are subscribed. There are also five tiers, including the free membership, with prices ranging from $1 to $330 per month, offering between 10 minutes and 40 hours of audio. The audio quality varies across the different packages, as does the ability to distribute commercially.

The UK-based company ElevenLabs got unicorn status in January 2024 after securing an $80 million Series B funding round, making it a serious player in the AI voice generation game. It also announced that it would be launching AI sound effects .

Mati Staniszewski, CEO and co-founder of ElevenLabs, said their goal is “to transform how we interact with content by breaking down language and communication barriers.” He added that the London-based voice cloning company hopes to build cutting-edge technology to make content accessible across languages and voices “to enable everyone to connect with information and stories that matter.”

The company has faced backlash in the past after it was blamed for deepfake robocalls of Joe Biden to New Hampshire voters.

VEED.IO is generally known as video editing software – it’s even named after it. However, it has recently introduced realistic text-to-speech AI voiceovers as well. Users can choose from a wide range of AI voices in multiple languages, but they must sign up for the service on a free plan. Unlike ElevenLabs, there are discrepancies when emphasizing certain words within sentences. Currently, up to 1,000 characters can be added per video project. Users can also translate their text into 60 different languages.

While there is a free option, the products come with watermarks. The paid tiers are for its video component, which ranges from £10 to £49 per month billed annually. The audio part of the software is free.

On their blog, VEED vice president of marketing Leila Woodington said : “The less time you have to spend on the routine parts of production, the more time you have to think about the storytelling and the craft.”

Murf.AI offers 10 minutes in its free trial, providing access to over 120 voices in its studio. Theoretically, depending on the selected voice, it allows users to alter the mood of the voice to include angry, conversational, inspirational, and sad tones. The availability of UK regional accents was particularly exciting to see. However, while the voice sounds somewhat robotic, the accents on certain words are accurate. Users are not able to download the recordings for free.

A cool feature offered by Murf , which isn’t provided by any other text-to-speech converter, is that it allows users to change their voice while recording. The voiceovers can be personalized based on pitch, speed, and volume. It even offers a tool to create Spotify ads.

It offers three tiers, including its free plan, with prices ranging from $23 to $79 per month when billed annually. Only the most expensive membership allows people to change their voices and integrate their works with Google Slides. However, both paid plans permit users to utilize their recordings for commercial purposes.

Like VEED.IO and Murf.AI, people have to sign up for PlayHT . What’s interesting about PlayHT is that each sample is unique and can be downloaded. The recording sounds fairly natural, though a little morose, and the software provides around 12,400 free characters.

It also has a voice cloning feature, integrations into WordPress, as well as custom pronunciations. However, this is not available on the free tier. The two paid plans are both billed yearly and are $31.20 and $99.

A YouTuber was reported to have used PlayHT to modify the AI-generated voice on a Pokédex to make it have the sound and cadence of the actual device in the show.

LOVO also requires registering and paying for its service before recordings can be downloaded, however, users can test out 180 characters without signing up. One of Lovo Studio’s standout features is its ability to generate natural-sounding voices in various languages. Whether users need English voiceovers or voices in different languages, LOVO Studio’s AI technology delivers voices that are remarkably human-like and emulate human speech effectively.

LOVO Studio provides a range of plans catering to different needs, starting with a free plan providing basic functionality. This allows users to explore the platform and its capabilities without any cost. The Pro plan is available for $48 per month for those seeking more features and customization options. The platform also offers premium voices for users looking for even higher quality and more distinct options, for $75 per month billed annually.

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.

Today, we’re launching Universal-1, our most powerful and accurate multilingual speech-to-text model to date—trained on 12.5M hours of multilingual audio data.

Today, AssemblyAI is launching Universal-1 ,  our most capable and highly trained speech recognition model. Trained on over 12.5 million hours of multilingual audio data, Universal-1 achieves best-in-class speech-to-text accuracy, reduces word error rate and hallucinations, improves timestamp estimation, and helps us continue to raise the bar as the industry-leading Speech AI provider. 

Universal-1 is trained on four major languages: English, Spanish, French, and German, and shows extremely strong speech-to-text accuracy in almost all conditions, including heavy background noise, accented speech, natural conversations, and changes in language, while achieving fast turn-around time and improved timestamp accuracy.

In the last few years we've seen an explosion of audio data available online. This coupled with advances in AI technology have allowed organizations to unlock the value of voice data in ways that were previously impossible. As a result, organizations are building new products, services, and capabilities that serve millions of people around the world. By building on AssemblyAI’s Speech AI models, customers have built products that can summarize video calls with clear notes and action items, automate customer service experiences and help organizations understand the voice of their customers with insights from every customer interaction, and create apps that help teachers guide students more effectively as they learn to read.

With Universal-1 we sought to build on the industry-leading performance of our previous models, and designed this new model guided by the idea that accuracy of every word matters. In conversations with customers, it was clear that there was a need in the industry for a model that focused on the nuances of spoken language across accents, tone, dialect, faithfulness, and more. We hope the new capabilities of Universal-1 will help power the next generation of AI products and features built with voice data.

Accuracy is paramount when deciding which speech-to-text model to implement. AssemblyAI's Automatic Speech Recognition (ASR) model is best-in-class, and we are beneficiaries of the constant improvements they implement, like Universal-1. We provide lead intelligence to over 200,000 small businesses. If the transcriptions are not accurate, then the downstream intelligence our customers depend on will also be subpar — garbage in, garbage out.

Ryan Johnson, Chief Product Officer, CallRail

Universal-1 ASR: Pushing the Boundaries of Speech AI

Universal-1 accomplishes the following improvements: 

Accurate and robust multilingual speech-to-text Universal-1 represents another major milestone in our mission to provide accurate, faithful, and robust speech-to-text capabilities for multiple languages, helping our customers and developers worldwide build various Speech AI applications.

• Universal-1 achieves 10% or greater improvement in English, Spanish, and German speech-to-text accuracy, compared to the next-best commercial speech-to-text system we tested.
• Universal-1 reduces hallucination rate by 30% over a widely used open-source model, Whisper Large-v3, providing users with confidence in the results we deliver.
• Humans prefer the outputs from Universal-1 over Conformer-2, our previous generation model, 71% of the time when they have a preference.
• Universal-1 exhibits the ability to code switch, transcribing multiple languages within a single audio file.

Precise timestamp estimation Word-level timestamps are essential for various downstream applications, such as audio and video editing. In conversation analytics and meeting transcription, accurate timestamps are crucial to enable speaker diarization to align speaker labels with recognized words.

• Word-level timestamps are essential for various downstream applications, such as audio and video editing as well as conversation analytics.
• Universal-1 improves our timestamp accuracy by 13% relative to Conformer-2.
• The improvement in timestamp estimation results in a positive impact on speaker diarization, improving concatenated minimum-permutation word error rate (cpWER) by 14% and speaker count estimation accuracy by 71% compared to Conformer-2.

Efficient parallel inference

• Effective parallelization during inference is crucial to achieve very low turnaround processing time for long audio files.
• Universal-1 achieves a 5x speed-up compared to a fast and batch-enabled implementation of Whisper Large-v3 on the same hardware.

My name is Angelica Skyler Alexander Hamilton. Where's your family from? Unimportant. There's a million things I haven't. Just you wait. Just you wait. So this is what it feels like to match wit for someone at your level. What the hell is the catch? It's the feeling of freedom. Of seeing the light is Ben Franklin with the key and a kite. You see it, right? The conversation lasted two minutes, maybe three minutes. Everything we said in total agreement. It's the dream and it's a bit of a dance, a bit of a posture. It's a bit of a stance. He's a bit of a flirt. But I'm gonna give it a chance. I asked about his family. Did you see his answer? His hands started fidgeting. He looked askance. He's penniless. He's flying by the seat of his pants. Handsome boy, does he know it. Peach fuzz. Then he can't even grow it. Want to take him far away from this place? Then I turn and see my sister's face. And she is helpless. And I know she is helpless. And her eyes are just helpless. And I realize three fundamental truths at the exact same time.

Universal-1’s training data far exceeds the training data used for most existing speech-to-text models. This training data includes audio from non-native speakers, audio with heavy background noise, conversations involving multiple talkers held in various domains and settings, to better simulate how speech happens in the real world. Universal-1 also builds on our predecessor models, Conformer-1 and Conformer-2, to capture proper nouns and alphanumeric details with high accuracy. 

We’re excited to see the impact that Universal-1 has on applications like:

• Conversational intelligence platforms that are now able to analyze vast amounts of customer data quickly, accurately, and reliably in order to surface critical voice of customer insights and analytics regardless of accent, recording condition, number of speakers, and more.
• AI notetakers that can now generate highly accurate and hallucination-free meeting notes to serve as the basis for LLM-powered summaries, action items, and other metadata generation with accurate proper noun, speaker, and timing information included.
• Creator tool applications that are now able to build AI-powered video editing workflows for their end-users leveraging precise speech-to-text outputs in multiple languages with low error rates and reliable word timing information.
• Telehealth platforms automating clinical note entry and claims submission processes with a high success rate leveraging accurate and faithful speech-to-text outputs, including rare words like prescription names and medical diagnoses, in adversarial and far field recording conditions.

Untangling Disinformation

Using ai to detect ai-generated deepfakes can work for audio — but not always.

As deepfake generation technology improves and leaves ever-fewer telltale signs that humans can rely on, computational methods for detection are becoming the norm. But technological solutions are no silver bullet for the problem of detecting AI-generated voices. Aaron Marin for NPR hide caption

As deepfake generation technology improves and leaves ever-fewer telltale signs that humans can rely on, computational methods for detection are becoming the norm. But technological solutions are no silver bullet for the problem of detecting AI-generated voices.

Artificial intelligence is supercharging audio deepfakes , with alarm bells ringing in areas from politics to financial fraud.

The federal government has banned robocalls using voices generated by AI and is offering a cash prize for solutions to mitigate harms from voice cloning frauds . At the same time, researchers and the private sector are racing to develop software to detect voice clones, with companies often marketing them as fraud-detection tools.

The stakes are high. Detection software getting it wrong can carry serious implications.

It takes a few dollars and 8 minutes to create a deepfake. And that's only the start

"If we label a real audio as fake, let's say, in a political context, what does that mean for the world? We lose trust in everything," says Sarah Barrington, an AI and forensics researcher at the University of California, Berkeley.

"And if we label fake audios as real, then the same thing applies. We can get anyone to do or say anything and completely distort the discourse of what the truth is."

As deepfake generation technology improves and leaves ever-fewer telltale signs that humans can rely on, computational methods for detection are becoming the norm.

But an NPR experiment indicated that technological solutions are no silver bullet for the problem of detecting AI-generated voices.

Probably yes? Probably not

NPR identified three deepfake audio detection providers — Pindrop Security , AI or Not and AI Voice Detector . Most claim their tools are over 90% accurate at differentiating between real audio and AI-generated audio. Pindrop only works with businesses, while the others are available for individuals to use.

5 tips for not getting tricked online this April Fools' Day — and beyond

NPR submitted 84 clips of five to eight seconds to each provider. About half of the clips were snippets of real radio stories from three NPR reporters. The rest were cloned voices of the same reporters saying the same words as in the authentic clips.

The voice clones were generated by technology company PlayHT. To clone each voice, NPR submitted four 30-second clips of audio — one snippet of a previously aired radio story of each reporter and one recording made for this purpose.

Our experiment revealed that the detection software often failed to identify AI-generated clips, or misidentified real voices as AI-generated, or both. While Pindrop Security's tool got all but three samples correct, AI or Not's tool got about half wrong, failing to catch most of the AI-generated clips.

The verdicts these companies provide aren't just a binary yes or no. They give their results in the form of probabilities between 0% and 100%, indicating how likely it is that the audio was generated by AI.

AI-generated images are everywhere. Here's how to spot them

AI Voice Detector's CEO, Abdellah Azzouzi, told NPR in an interview that if the model predicts that a clip was 60% or more likely to be generated by AI, then it considers the clip AI-generated. Under this definition, the tool wrongly identified 20 out of the 84 samples NPR submitted.

AI Voice Detector updated its website after the interview. While the probability percentages for most previously tested clips remained the same, they now include an additional note laying out a new way of interpreting those results. Clips flagged as 80% or more are now deemed "highly likely to be generated by AI." Those scoring between 20% and 80% are "inconclusive." Clips rated less than 20 are "highly likely to be real."

That panicky call from a relative? It could be a thief using a voice clone, FTC warns

In an email to NPR, the company did not respond to NPR's questions about why the thresholds changed, but says it's "always updating our services to offer the best to those who trust us." The company also removed the claim from its website that the tool was more than 90% accurate.

Under these revised definitions, AI Voice Detector's tool got five of the clips NPR submitted wrong and returned inconclusive results for 32 clips.

While the other providers also provide results as probabilities, they did not provide results marked as inconclusive.

Using AI to catch AI

While NPR's anecdotal experiment is not a formal test or academic study, it highlights some challenges in the tricky business of deepfake detection.

AI images and conspiracy theories are driving a push for media literacy education

Detection technologies often involve training machine learning models. Since machine learning and artificial intelligence are virtually the same technology, people also call this approach "using AI to detect AI."

Barrington has both tested various detection methods and developed one with her team. Researchers curate a dataset of real audio and fake audio, transforming each into a series of numbers that are fed into the computer to analyze. The computer then finds the patterns humans cannot see to distinguish the two.

"Things like in the frequency domain, or very sort of small differences between audio signals and the noise, and things that we can't hear but to a computer are actually quite obvious," says Barrington.

Amit Gupta, head of product at Pindrop Security, says one of the things their algorithm does when evaluating a piece of audio is to reverse-engineer the vocal tract — the actual physical properties of a person's body — that would be needed to produce the sound. They called one fraudster's voice that they caught "Giraffe Man."

The FCC says AI voices in robocalls are illegal

"When you hear the sequence of sound from that fraudster, it is only possible for a vocal tract where a human had a 7-foot-long neck," Gupta says. "Machines don't have a vocal tract. ... And that's where they make mistakes."

Anatoly Kvitnitsky, CEO of AI or Not, says his company trains its machine learning model based on clients' specific-use cases. As a result, he said, the general-use model the public has access to is not as accurate.

"The format is a little bit different depending on if it's a phone call ... if it's a YouTube video. If it's a Spotify song, or TikTok video. All of those formats leave a different kind of trace."

Tech giants pledge action against deceptive AI in elections

While often better at detecting fake audio than people, machine learning models can easily be stumped in the wild. Accuracy can drop if the audio is degraded or contains background noise. Model makers need to train their detectors on every new AI audio generator on the market to detect the subtle differences between them and real people. With new deepfake models being released frequently and open source models becoming available for everyone to tweak and use, it's a game of whack-a-mole.

After NPR told AI or Not which provider it used to generate the deepfake audio clips, the company released an updated detection model that returned better results. It caught most of the AI clips, but also misidentified more real voices as AI. Its tool cannot process some other clips and returned error messages.

What's more, all of these accuracy rates only pertain to English-language audio. Machine learning models need to analyze real and fake audio samples from each language to tell the difference between them.

Meta will start labeling AI-generated images on Instagram and Facebook

While there seems to be an arm's race between deepfake voice generators and deepfake voice detectors, Barrington says it's important for the two sides to work together to make detection better.

ElevenLabs, whose technology was used to create the audio for the deepfake Biden robocall , has a publicly available tool that detects its own product. Previously, the website claimed that the tool also detects audio generated by other providers, but independent research has shown poor results. PlayHT says a tool to detect AI voices — including its own — is still under development.

Detection at scale isn't there yet

Tech giants including major social media companies such as Meta, TikTok and X have expressed their interest in "developing technology to watermark, detect and label realistic content that's been created with AI." Most platforms' efforts seem to focus more on video, and it's unclear whether that would include audio, says Katie Harbath, chief global affairs officer at Duco Experts, a consultancy on trust and safety.

AI fakes raise election risks as lawmakers and tech companies scramble to catch up

In March, YouTube announced that it would require content creators to self-label some videos made with generative AI before they upload videos. This follows similar steps from TikTok . Meta says it's also going to roll out labeling on Facebook and Instagram, using watermarks from companies that produce generative AI content.

Barrington says specific algorithms could detect deepfakes of world leaders whose voices are well known and documented, such as President Biden. That won't be the case for people who are less well known.

"What people should be very careful about is the potential for deepfake audio in down-ballot races," Harbath says. With less local journalism and with fact-checkers at capacity, deepfakes could cause disruption.

AI-generated deepfakes are moving fast. Policymakers can't keep up

As for scam calls impersonating loved ones, there's no high-tech detection that flags them. You and your family can come up with questions a scammer wouldn't know the answer to in advance, and the FTC recommends calling back to make sure the call was not spoofed.

"Anyone who says 'here's an algorithm,' just, you know, a web browser plug-in, it will tell you yes or no — I think that's hugely misleading," Barrington says.
