Actors union backs Scarlett Johansson after claim of voice misuse by OpenAI

SAG-AFTRA, an influential body representing television and radio artists, on Tuesday backed Scarlett Johansson after the American actress raised concerns over the voice feature of a new OpenAI system that she said sounded “eerily similar” to her own.

OpenAI unveiled its latest artificial intelligence model, GPT-4o, last week, featuring an audio-interacting persona named “Sky”.

Johansson said on Monday that she had previously turned down a request from the company to use her voice for this system.
