Arizona State University researchers found that actress Scarlett Johansson’s voice is very similar to OpenAI GPT-4o’s Sky in many nuances. It was found that Johansson’s voice is more similar than the voice of 98 percent of the other actresses compared.

At the same time, it was found that the voices of actresses Anne Hathaway and Keri Russell resembled Sky’s even more at times. Johansson’s voice shares similarities in vocal tract length but is slightly more breathy, while Sky’s voice is higher and more expressive.

Despite OpenAI executives denying that Sky was meant to sound like Johansson, Johansson revealed that OpenAI CEO Sam Altman asked her to lend her voice to the model, but she declined.

Johansson has hired legal counsel but has yet to take legal action against OpenAI. Legal experts believe he could have a strong case if he decides to sue.
