Meta’s new AI models can recognize and produce speech for more than 1,000 languages

They educated it on two new information units: one which incorporates audio recordings of the New Testomony Bible and its corresponding textual content taken from the web in 1,107 languages, and one other containing unlabeled New Testomony audio recordings in 3,809 languages. The workforce processed the speech audio and the textual content information to enhance its high quality earlier than operating an algorithm designed to align audio recordings with accompanying textual content. They then repeated this course of with a second algorithm educated on the newly aligned information. With this methodology, the researchers have been in a position to educate the algorithm to be taught a brand new language extra simply, even with out the accompanying textual content.

“We are able to use what that mannequin discovered to then shortly construct speech methods with very, little or no information,” says Michael Auli, a analysis scientist at Meta who labored on the undertaking.

“For English, we now have heaps and many good information units, and we now have that for a number of extra languages, however we simply don’t have that for languages which might be spoken by, say, 1,000 folks.” 

The researchers say their fashions can converse in over 1,000 languages however acknowledge greater than 4,000. 

They in contrast the fashions with these from rival corporations, together with OpenAI Whisper, and declare theirs had half the error charge, regardless of masking 11 occasions extra languages.

Nevertheless, the workforce warns the mannequin remains to be prone to mistranscribing sure phrases or phrases, which might end in inaccurate or probably offensive labels. Additionally they acknowledge that their speech recognition fashions yielded extra biased phrases than different fashions, albeit solely 0.7% extra. 

Whereas the scope of the analysis is spectacular, using non secular texts to coach AI fashions may be controversial, says Chris Emezue, a researcher at Masakhane, a corporation engaged on natural-language processing for African languages, who was not concerned within the undertaking.

“The Bible has a whole lot of bias and misrepresentations,” he says.
