The dispute between OpenAI and actress Scarlett Johansson shows how well AI can now imitate human voices. OpenAI had given its AI ChatGPT a female voice called ‘Sky’ with an update. This sounded very similar to Scarlett Johansson, as many users thought. She had reportedly turned down an official request to ‘lend’ her voice to ChatGPT a few months earlier. Although OpenAI assured that it had not cloned Johansson's voice, the actress is now having this legally checked.
