OpenAI has decided to stop using chatbot ChatGPT's virtual voice 'Sky' after Scarlett Johansson expressed her dissatisfaction over its similarity to her voice. The voice was part of a recently launched improved version of ChatGPT. Johansson, who had rejected an offer from OpenAI to provide the voice, felt compelled to consider legal action. OpenAI director Sam Altman denied that the company was trying to imitate Johansson's voice, but out of respect the use of Sky's voice has stopped.
