Researchers at Arizona State College discovered that Scarlett Johansson’s voice does certainly sound like “Sky,” OpenAI’s currently discontinued GPT-4o voice, according to NPR, which commissioned the comparability. After utilizing AI fashions developed to research vocal similarities to match Sky to roughly 600 different actresses, the lab reportedly discovered Johansson’s voice was “extra just like Sky than 98% of the opposite actresses.”
However the fashions additionally “typically” discovered that the voices of Anne Hathaway and Keri Russell resembled Sky’s greater than did Johansson’s. Visar Berisha, the professor who led the evaluation, advised NPR that Johansson’s voice is “related, however probably not similar.” Berisha’s different work contains OriginStory (PDF), an FTC challenge-winning microphone that watermarks voice recordings as human-created.
However, the researchers reportedly concluded there have been “simple commonalities” between the voices. As an example, the evaluation reportedly confirmed that Sky’s and Johansson’s vocal tracts would have “similar” lengths (“vocal tract” refers back to the throat, mouth, and nasal passages that might produce a given voice).
Some variations included that Sky’s voice was just a little higher-pitched and extra expressive than Johansson’s, whereas hers is “barely extra breathy” than that of the mannequin, in line with NPR. We requested Berisha for extra data on his evaluation and its limitations, and can replace if he responds. OpenAI didn’t instantly reply to a request for remark.
Each OpenAI CEO Sam Altman and CTO Mira Murati have denied that Sky is meant to sound like Johansson. After its GPT-4o demo earlier this month — after which Altman revealed a one-word post that merely learn “her” — Johansson said that Altman had requested her to lend her voice to the mannequin, which she declined, and that he tried once more as just lately as two days previous to the demo.
