GOOGLE and a re­search group from the Univer­sity of Ox­ford have been work­ing on an AI sys­tem that can read lips, ap­par­ently with bet­ter suc­cess than hu­mans. Lip- read­ing is not a com­mon skill. But peo­ple with hear­ing im­pair­ments of­ten learn it and, along with hear­ing aids, man­age to un­der­stand what oth­ers are say­ing. Now things could be a lot eas­ier if Google pro­vides ac­cess to the tech­nol­ogy.

In­ter­est­ingly, a deep learn­ing sys­tem was ex­posed to 5,000 hours of BBC tele­vi­sion shows. It in­volved 1,18,000 sen­tences, ac­cord­ing to a study ti­tled Lip Read­ing Sen­tences in the Wild, and re­sults have shown that the sys­tem is out­per­form­ing hu­mans at this skill. The study en­vis­ages ap­pli­ca­tions such as dic­tat­ing to a phone in a noisy en­vi­ron­ment, trans­la­tion and tran­scrip­tion, re­dub­bing films, re­solv­ing mul­titalker speech and gen­er­ally im­prov­ing speech recog­ni­tion.
