OpenAI has removed one of the voices used by ChatGPT 4o after it was likened to the actress Scarlett Johansson and the character she played in the 2013 movie Her. The US artificial intelligence research firm is “working to pause” the voice of ‘Sky’ which responds to ChatGPT users, while it addresses the situation around the similarity to the Hollywood star. In Her, Theodore (Joaquin Phoenix) falls in love with his phone’s operating assistant, voiced by Johansson. OpenAI published a blog post setting out that “AI voices should not deliberately mimic a celebrity’s distinctive voice” as well as denying Sky’s tones were an imitation of the highest-grossing box office female talent of all time, but instead “belongs to a different professional actress using her own natural speaking voice.” The detailed statement outlined how the company “worked closely with the voice acting industry to ensure we took the right steps to cast ChatGPT’s (five) voices.” It added how each actor “receives compensation above top-of-market rates”, and “to protect their privacy, we cannot share the names of our voice talents”. At present, it is unclear if OpenAI will permanently remove Sky as a voice assistant or if any amendments will be made. We’ve heard questions about how we chose the voices in ChatGPT, especially Sky.
