Scarlett Johansson has taken a vocal stand on artificial intelligence, after having her likeness and voice used without permission.

Last year, Johansson said she had been asked to voice OpenAI’s Chatbot by CEO Sam Altman, but turned down the job, only for people to notice that the feature, named “Sky,” sounded almost exactly like the actress.

“Particularly with the A.I. piece. It was like: If that can happen to me, how are we going to protect ourselves from this? There’s no boundary here; we’re setting ourselves up to be taken advantage of,” the 40-year-old told InStyle Magazine earlier this month.

In a statement to NPR following the release of “Sky,” Johansson said, “When I heard the released demo, I was shocked, angered and in disbelief that Mr. Altman would pursue a voice that sounded so eerily similar to mine that my closest friends and news outlets could not tell the difference. Mr. Altman even insinuated that the similarity was intentional, tweeting a single word ‘her’ – a reference to the film in which I voiced a chat system, Samantha, who forms an intimate relationship with a human.”
