Morgan Freeman has voiced strong criticism against a scam operation that uses an AI-generated version of his voice.

Taking to his social media account on Friday, the Seven actor, known for his distinctive voiceover work, expressed his appreciation for fans who have notified him about AI-generated imitations of his voice.

“Thank you to my incredible fans for your vigilance and support in calling out the unauthorized use of an A.I. voice imitating me,” Freeman posted to X (formerly Twitter) on Friday.

He added, “Your dedication helps authenticity and integrity remain paramount. Grateful.”

In his post, Freeman included the hashtags “#scam” and “#IdentityProtection.”

This message reportedly came in response to a media source stating that a TikTok user claiming to be Freeman’s niece recently uploaded videos to the social media site with what seems to be an AI-generated version of the actor’s voice narrating them.

Freeman, known for his work as the voice of CBS News, has also narrated for the Netflix series Life on Our Planet and the movie March of the Penguins.

Earlier, Scarlett Johansson had threatened to take legal action against OpenAI last month for allegedly stealing and mimicking her voice after she refused to give a license to use it. Johansson stated that the Sam Altman-founded startup imitated her voice after she rejected OpenAI’s request for her to be the voice of “Sky” for their AI system.
