Voice cloning is without doubt one of the areas quickly rising because of generative AI. The time period refers to replicating an individual’s vocal stylings — pitch, timbre, rhythms, mannerisms, and distinctive pronunciations — by know-how.
Whereas startups together with ElevenLabs have obtained tens of tens of millions in funding for dedicating themselves to this pursuit, Meta Platforms, the guardian firm of Fb, Instagram, WhatsApp and Oculus VR has launched its personal free voice cloning program, Audiobox — with a catch.
Unveiled right now on Meta’s web site by researchers working on the Fb AI Analysis (FAIR) lab, Audiobox is described as a “new foundation research model for audio generation” construct atop its earlier work on this space, Voicebox.
“It can generate voices and sound effects using a combination of voice inputs and natural language text prompts — making it easy to create custom audio for a wide range of use cases,” reads the Audiobox webpage.

Merely sort in a sentence that you really want a cloned voice to say, or an outline of a sound you need to generate, and Audiobox will do the remainder. Customers may also document their very own voice and have it cloned by Audiobox.
A ‘family’ of audio producing AIs
Meta additional famous that it really created a “family of models,” one for speech mimicry and the opposite for producing extra ambient sounds and sound results similar to canine barking or sirens or kids taking part in, and that they’re all “built upon the shared self-supervised model Audiobox SSL.”
Self-supervised studying (SSL) is a machine studying (ML) deep studying approach during which synthetic intelligence algorithms are assigned to generate their very own labels for information that’s unlabeled, versus supervised studying, the place the information might already be labeled.
The researchers printed a scientific paper explaining a few of their methodology and rationale for taking an SSL method, writing “because labeled data are not always available or of high quality, and data scaling is the key to generalization, our strategy is to train this foundation model using audio without any supervision, such as transcripts, captions, or attribute labels, which can be found in larger quantities.”
After all, most main generative AI fashions are closely depending on human generated information for coaching learn how to create new content material, and Audiobox is not any exception. The FAIR researchers relied upon “160K hours of speech (primarily English), 20K hours of music and 6K hours of sound samples.”
“The speech portion covers audiobooks, podcasts, read sentences, talks, conversations, and in-the-wild recordings including various acoustic conditions and non-verbal voices. To ensure fairness and a good representation for people from various groups, it includes speakers from over 150 countries speaking over 200 different primary languages.”
The analysis paper doesn’t specify precisely the place this information was sourced from and whether or not or not it was within the public area, however that’s certainly an vital query with numerous artists, authors, and music publishers suing a bunch of AI corporations for coaching on probably copyrighted materials with out the creators/rights house owners’ categorical consent. We’ve reached out to a Meta spokesperson for clarification and can replace once we obtain it.
You’ll be able to attempt it your self and clone your personal voice now
To showcase the capabilities of Audiobox, Meta has additionally launched a bunch of interactive demos, together with one that allows you to document the audio of the person talking a couple of sentence’s value of textual content and replicates their voice.
Then, the person can sort in textual content that they need their cloned voice to say and listen to it learn again to them of their cloned voice.
You’ll be able to attempt it for your self right here. In my case, the ensuing AI generated cloned audio was eerily related, although not precisely the identical as my very own voice (as testified by my spouse and youngster, who heard it not figuring out what it was).
Meta additionally permits customers to generate complete new voices from textual content descriptions of what they need to sound like “deep feminine voice” “high pitched masculine speaker from the U.S.” and so on., in addition to restyle voices recorded by the person, or sort in a textual content immediate to generate complete new sound. I attempted the latter with “dogs barking” and obtained two variations that have been indistinguishable to the true factor in my ears.
Now for the massive catch: Meta features a disclaimer with its Audiobox interactive demos noting that “this is a research demo and may not be used for any commercial purpose(s),” and moreover, that it’s restricted to these outdoors of “the States of Illinois or Texas,” which have state legal guidelines that apparently prohibit the type of audio assortment Meta is doing for the demos.
Apparently, like its new Think about by Meta AI picture era net app unveiled final week, Audiobox additionally isn’t open supply, bucking Meta’s dedication to the sector that was evidenced earlier by the discharge of its Llama 2 household of huge language fashions (LLMs). We additionally requested our Meta contact about this and whether or not Audiobox can be made open supply sooner or later and can replace once we obtain a response.
So, the know-how can’t be used for any moneymaking/enterprise functions — nor can it’s utilized by residents of two of probably the most populous states within the U.S. — for now. However with AI advancing at a speedy clip, anticipate this to vary and there to be business variations within the close to future, if not from Meta, from others.
