Del declined to comment about whether the Carlin-sounding voice was generated by A.I.

I bet they used an AI trained on Carlin’s work to create this special, but Lugosi v. Universal Pictures, IMO (IANAL) means Carlin’s family will likely lose a suit based on imitating his likeness. Good thing I’m not a lawyer because apparently there’s several laws now, starting with the “California Celebrities Rights Act” meaning likeness rights are inherited and good for 70 years.
