I googled "Ford v. Milton" and found something regarding the "slayer's rule", which is unlikely to be what you were referring to...
The whole point I made was that it was not her "likeness". Except in the way that the voice of any young woman speaking clearly resembles the voice of any other young woman speaking clearly, because I would argue that if you took 10 random young women's voices who speak clearly (say, 10 voice actresses) and listened to them all together, you wouldn't be able to distinguish them much either.
>a United States Court of Appeals case in which Bette Midler sought remedy against Ford Motor Company for a series of commercials in the 1980s which used a Midler impersonator. The case brought into question if a unique feature, such as a voice, can distinguish someone and thus must be authorized for impersonation.
Wow, interesting and relevant case! I am very narrowly on the side of Midler here, only because they ALSO used her song (and even though the copyright owner of the song agreed to it). I don't think OpenAI's use of the other voice actress falls under the purview of this case though.
If I was defending such a case (IANAL), I'd hire 10 voice actresses of the same age and record them saying the same thing and see if the jury could detect the differences among them and to what degree.
