A company can't take a photo from your Facebook and plaster it across an advertisement for their product without you giving them the rights to do that.
And if you're a known public figure, this includes lookalikes and soundalikes as well. You can't hire a ScarJo impersonator that people will think is ScarJo.
This is clearly a ScarJo soundalike. It doesn't matter whether it's an AI voice or clone or if they hired someone to sound just like her. Because she's a known public figure, that's illegal if she hasn't given them the rights.
(However, if you generate a synthetic voice that just happens to sound exactly like a random Joe Schmo, it's allowed because Joe Schmo isn't a public figure, so there's no value in the association.)
Just find someone who sounds like her, then hire them for the rights to their voice.
