Right, but one can imagine a popular film about AI casting a voice actor not because the voice actor has an appealing or soothing voice, but because the actor is themselves very popular and will draw a large audience. Perhaps say Arnold Schwarzenegger is cast and OpenAI decides to create a voice very similar to the one Arnold uses in that movie because OpenAI wants to leverage the fame associated with that movie, that character, or Arnold himself. In that case the argument would be very strong that OpenAI is taking advantage of personality rights as opposed to mimicking a nice sounding voice that suits their product. According to your argument, Scarlett Johansson was not cast in Her because something about her personhood would draw audiences to the movie, or something about her personality and character was being leveraged, but rather that her voice has some nice technical properties that made it a suitable choice for the movie. In that case, the argument is less strong that OpenAI is infringing on Scarlett's personality rights, and more the case that they liked the properties and qualities that her voice has, and when she specifically turned down the offer to lend her voice to OpenAI, OpenAI found someone else who had similar properties and qualities as a replacement.
