Researchers at Arizona State University discovered that Scarlett Johansson’s voice closely resembles the now discontinued GPT-4o voice, Sky, from OpenAI. The analysis found that Johansson’s voice was more similar to Sky than 98% of other actresses, but also noted similarities with Anne Hathaway and Keri Russell. The study highlighted identical vocal tract lengths but mentioned differences in pitch and expressiveness between Sky and Johansson.

OpenAI CEO Sam Altman and CTO Mira Murati have denied any intention for Sky to sound like Johansson. Johansson revealed that Altman had asked her to provide her voice for the model, which she declined multiple times. Despite these denials, the study confirmed undeniable commonalities between Johansson’s voice and Sky, although some differences in pitch and expressiveness were noted.
