According to documents and recordings, OpenAI hired an actress to create the voice for ChatGPT's 'Sky' months before contacting Scarlett Johansson, contradicting claims that they copied her voice. The voice in question bears an eerie resemblance to Johansson's character in the movie 'Her'. OpenAI's actions have sparked a debate about voice ownership and the potential for AI to replicate unique voices. The company has faced criticism and potential legal action over the issue.
