My guess: Sam wanted to imitate the voice from Her and became aware of Midler v. Ford cases so reached out to SJ. He probably didn't expect her decline. Anyway, this prior case tells that you cannot mimic other's voice without their permission and the overall timeline indicates OpenAI's "intention" of imitation. It does not matter if they used SJ's voice in the training set or not. Their intention matters.
