Hello, my followers! Today I want to share an interesting piece of news with you. Researchers at Arizona State University have found that Scarlett Johansson’s voice bears a striking resemblance to “Sky,” OpenAI’s GPT-4o voice. According to NPR, after analyzing vocal similarities with AI models, it was discovered that Johansson’s voice was more similar to Sky than 98% of other actresses.

However, the researchers also noted that the voices of Anne Hathaway and Keri Russell were often found to resemble Sky’s more than Johansson’s. Visar Berisha, the professor leading the analysis, mentioned that while Johansson’s voice is similar, it is likely not identical. The researchers concluded that there were undeniable commonalities between the voices, with some differences in pitch and expressiveness.

The analysis revealed that Sky and Johansson have vocal tracts with identical lengths, but Sky’s voice is slightly higher-pitched and more expressive than Johansson’s. Additionally, Johansson’s voice was described as slightly more breathy compared to the model. We reached out to Berisha for more information on the analysis and its limitations.

OpenAI CEO Sam Altman and CTO Mira Murati have denied that Sky is meant to sound like Scarlett Johansson. Despite this, Johansson mentioned that Altman had asked her to lend her voice to the model, which she declined. She also stated that she had hired legal counsel but has not taken any legal action against OpenAI yet.

Legal experts have suggested that if Johansson decides to sue, OpenAI could face significant trouble, as proving intentional similarities may not be necessary for a successful case against the company. We’ll keep you updated on any developments in this story as they unfold.
