A+ Copycat OpenAI’s controversial “Sky” voice for ChatGPT sounds remarkably similar to the voice of Scarlett Johansson, a forensic analysis has found, adding weight to what many already suspected and what Johansson herself has charged: that OpenAI deliberately mimicked the actress’s voice without her permission. The analysis, conducted by researchers at the Arizona State University and commissioned by NPR, used several AI models to evaluate similarities between the voices of Sky and about 600 actresses, including Johansson. Lo and behold, it found that Johansson’s voice was more similar to Sky than 98 percent of the other candidates. There are a few caveats, however. Johansson wasn’t always the top scorer, with the voices of Anne Hathaway and Keri Russell “often” being rated as more alike, according to NPR. Sky’s voice is slightly higher pitched and more expressive, too, while Johansson’s is breathier. But other parts of the analysis are damning, such as one that simulated the speakers’ vocal tracts based on the characteristics of their voice and found that Sky and Johansson would have identical tract lengths. Visar Berisha, a computer scientist at ASU who led the analysis, summed it up neatly. “Our analysis shows that the two voices are similar but likely not identical,” he told NPR. Sky-High Lies The controversy stems from a big update to ChatGPT released last month, which debuted a new voice assistant capable of real-time conversation. Sky was one of those voices, and soon enough, people took note of its resemblance to Johansson’s role in the…Forensic Analysis Finds Overwhelming Similarities Between OpenAI's Voice and Scarlett Johansson
