Arizona State College researchers have reportedly found that Scarlett Johansson’s voice does certainly sound like OpenAI’s now-discontinued GPT-4o voice “Sky” NPR, commissioned for comparability. In accordance with experiences, after utilizing a man-made intelligence mannequin developed to research voice similarities and evaluating Sky to roughly 600 different actresses, the lab discovered that Johnson’s voice was “extra just like Sky than 98% of different actresses.”
However the mannequin additionally “usually” discovered that Anne Hathaway and Keri Russell’s voices have been extra just like Skye’s than Johnson’s. Professor Visar Berisha, who led the evaluation, mentioned NPR Johnson’s voice was “related, however most likely not the identical.” Berisha’s different works embody OriginStory (PDF), an FTC-challenged microphone that provides a watermark to human-created recordings.
Nonetheless, the researchers reportedly concluded that there have been “plain commonalities” between the voices. For instance, evaluation reportedly confirmed that Skye and Johnson had “the identical” vocal tract size (the “vocal tract” refers back to the throat, mouth, and nasal cavities that produce particular sounds).
A number of the variations reportedly included that Skye’s voice was larger and extra expressive than Johnson’s, whereas her voice was “barely extra breathy” than the mannequin’s. NPR. We requested Berisha for extra details about his evaluation and its limitations and can replace if he responds. OpenAI didn’t instantly reply to a request for remark.
OpenAI CEO Sam Altman and chief know-how officer Mira Murati each denied that Sky supposed to sound like Johansson. After a demo of GPT-4o earlier this month, through which Altman printed a one-word put up that merely learn “her,” Johnson mentioned Altman had requested her to voice the mannequin, however she refused and he tried once more. As soon as simply two days earlier than the demo.
