All About AI Voice Cloning and 11 Best Tools For You

Do not index

Consider you've just lost a loved one. You go through their things and come across old voice messages. You take a moment to listen and recall happy memories. But what if you could hear them speak again? Not just through old recordings, but have a computer generated a voice that sounded exactly like them? AI voice cloning can do just that.

This innovative technology quickly analyzes voice data and creates a synthetic version miming a target speaker's unique tone, pitch, cadence, and inflections. But, what is text to speech and voice cloning? Voice cloning, or voice synthesis, is an advanced text-to-speech technology that generates speech in a human-like voice. And while this technology raises ethical questions, it also offers incredible benefits for those grieving the loss of a loved one.

This guide will explore AI voice cloning, how it works, its applications, and its pros and cons. You’ll also discover CoeFont’s AI voice changer, a tool that can help you generate voices that sound just like your favorite celebrity or a lost loved one.

What Is AI Voice Cloning?

Voice cloning generates an artificial imitation of a person's voice. Current AI software can create synthetic speech closely resembling a targeted human voice. Sometimes, the difference between the real and fake voice is imperceptible to the average person. If you understand video deepfakes, AI voice cloning is the equivalent of speech. With only a few minutes of recorded speech, developers can build an audio dataset to train an AI voice model to read any text in the target voice.

How Voice Cloning Works

Neural network-based TTS models mimic how the brain operates and efficiently learn patterns in data. While different approaches to using deep learning in synthetic voices exist, most result in better pronunciation of words and capturing subtleties like speed and intonation to create more human-like speech.

AI Voice Cloning: What Is It and How Does It Work?

AI voice cloning uses vocal samples and machine learning to produce a digital copy of a voice. First, the voice cloning software analyzes recordings of the target voice. Then, it creates a model that can generate speech with the same characteristics as the original voice. The more data you feed the system, the more realistic and customizable the voice it generates will be.

8 Incredible Use Cases of AI Voice Cloning

1. Restore Natural Communication for Those Who Lost Their Voice

Medical conditions like amyotrophic lateral sclerosis (ALS), autism, strokes, and traumatic brain injuries can severely impact a person’s ability to communicate. When a patient has an opportunity to bank their voice before losing it completely, voice cloning can recreate their original voice.

Even those who have never spoken can benefit from voice cloning. Crowdsourced speech samples from people who can’t talk usually match those likely to sound similar. This way, we can give even the most nonverbal individuals a voice.

Example

Project Revoice is an initiative that helped ALS patient Pat Quinn regain his voice by using voice banking and AI to clone his original voice before losing his ability to speak.

2. Help Professionals Build Trust with Digital Avatars

Voice is critical in establishing relationships between healthcare professionals and their patients. It helps elicit trust, particularly in online settings where physical distancing is required. Voice cloning can help build digital avatars that can interact with patients. These avatars can be programmed with the voice of a patient’s regular healthcare provider, helping to build trust and continuity in telehealth services.

Example

Sensely is a digital health platform that uses AI-driven avatars to interact with patients.

3. Streamline the Recording Process for Brand Voice Actors

Voice cloning can help voice actors work more efficiently as brand voices. Brand voices frequently have to record phone trees for interactive voice response systems or various scripts for corporate training videos. They also deal with the mistakes and modifications encountered in voiceover scripts if necessary. Voice cloning reduces the need for additional recordings, and thus allows actors to make better, more creative use of their time.

Example

David Attenborough's AI Voice. A voice clone of David Attenborough was created using AI for a documentary called The Mating Game. The clone was used to narrate parts of the documentary that the legendary broadcaster couldn’t record due to time constraints.

4. Make Online Learning Courses More Interactive

The importance of this use case for voice cloning with AI is also more salient during lockdowns. Voice conversion technology makes it easier to record audio notes because it makes it unnecessary to do so for every new session or to address the mistakes in previous sessions. The operational costs of professionally recorded lectures are dramatically reduced, and students can really benefit from the educational materials as if they were in a regular classroom.

Example

Descript’s Overdub. This tool allows content creators and educators to clone their voices, enabling them to edit and update their audio content seamlessly without needing to re-record everything. Educators can use this to create consistent, high-quality audio for online courses.

5. Replicate Voices for Film and Television

Voice synthesis helps you to dub an actor’s voice in post-production or to bring back on screen the voice of an actor who has sadly passed away. The former is a great way to save time because you no longer need to wait until a hard-to-get actor can come to the recording studio. Speech synthesis technology allows you to scale voices and record new lines anytime.

This means you are no longer tied to strict adherence to the original script, for example, Val Kilmer in Top Gun: Maverick. Val Kilmer, who lost his voice due to throat cancer, had his voice recreated using AI technology for the movie Top Gun, Maverick. The AI was trained on old recordings of Kilmer’s voice to produce new lines for his character.

6. Help Game Developers Create Unique Experiences

If high-demand actors know that they wouldn’t have to spend ages in the recording studio since their cloned voice can ‘take over,’ it makes it more likely that they will consider working with you for a game.

No more “now or never” since voice cloning offers more flexibility, allowing you to make changes after the recordings. The ability to ‘give old voices new life’ is also beneficial for game developers, whether you speak about adding historical voices to the game script or simply being able to finish the game with an actor who unfortunately passed away.

Example

James Earl Jones’ Darth Vader Voice. James Earl Jones, the iconic voice of Darth Vader, allowed the use of AI voice cloning to continue voicing Darth Vader in future Star Wars projects. The AI model was trained on his voice from past films, enabling the character to live on even as Jones steps back from active recording.

7. Set the Perfect Tone for Advertisements

Voice cloning streamlines the workflow for the production of advertisements. All you need to start a commercial video is a high-quality recording of the voice you’d like to replicate. Replication allows using voices that would otherwise be difficult to record, e.g., unavailable actors, kids, and historical figures. This can contribute significantly to lowering production time and costs.

Example

Coca-Cola’s Use of AI Voice. Coca-Cola has experimented with AI voice technology to create synthetic voices for its advertisements, allowing it to use consistent brand voices across different markets without needing constant re-recording.

8. Ditch the Dull Dubbing Process

Voice conversion technology saves time you would otherwise have to invest in voiceover work during post-production. Given the monotony of this process, nerve savings are relevant among the benefits of using voice synthesis.

If you use a language-agnostic technology, you can easily record the voice you need in any language and then simply translate it in an automated fashion. You can also be more adaptable to your target audience by using precisely the accent that’s presumably best received in a particular region.

Example

Netflix’s AI Dubbing. Netflix has explored AI voice cloning technology for dubbing, aiming to create more natural and accurate voice matches for different languages. This technology could significantly streamline the dubbing process for international releases.
