Sir David Attenborough doesn’t agree with AI being used to replicate his voice.

In a BBC News segment on Sunday, an AI recreation of the famed British broadcaster’s voice talking about its new series “Asia” was played alongside a real recording, with little to no difference between the two. BBC researchers had found the AI-generated Attenborough on a website and said there were several claiming to clone his voice.

In response, the 98-year-old sent the following statement to BBC News: “After a lifetime of trying to speak what I believe to be the truth, I am deeply disturbed to discover that my identity is being stolen by others today. and strongly object to their using it to say whatever they please.

The AI-generated Attenborough then made a response, which BBC News played. “Let’s set the record straight. Unless Mr. Attenborough has been working for us secretly and under an assumed name with work authorization in the United States, he is not on our payroll,” the report said. ‘I’m not David Attenborough. We’re both men, definitely British voices. I’m no David Attenborough though, for anyone who might be confused.

Dr. Jennifer Williams, an AI audio researcher at the University of Southampton, then gave her opinion on the matter after BBC News played another clip of the cloned voice talking about Donald Trump’s appointment of Matt Gaetz and the war in Ukraine.

“I’m a little disgusted by it,” she said. ‘This is very serious… when you have a trusted voice like Sir David Attenborough, who is recognized by people all over the world as an authority, as a voice of truth. And then to have words in his mouth about war, politics and things he never said or perhaps doesn’t even endorse is very worrying.
