NEW YORK (AP) — OpenAI says it plans to halt the use of one of its ChatGPT voices after some users said it sounded like Scarlett Johansson, who famously voiced a fictional, and at the time futuristic, AI assistant in the 2013 film “Her.”

In a post on the social media platform X Monday, OpenAI said it is “working to pause” Sky — the name of one of five voices that ChatGPT users can chose to speak with. The company said it had “heard questions” about how it selects the lifelike audio options available for its flagship artificial intelligence chatbot, particularly Sky, and wanted to address them.

OpenAI was also quick to debunk the internet’s theories about Johansson in an accompanying blog post detailing how ChatGPT’s voices were chosen.

“We believe that AI voices should not deliberately mimic a celebrity’s distinctive voice — Sky’s voice is not an imitation of Scarlett Johansson but belongs to a different professional actress using her own natural speaking voice,” the company wrote. It said it could not share the name of its voice actors for privacy reasons.
