I mostly agree with you, but I actually don't think it matters if it sounded exactly like her or not. The crime is in the training: did they use her voice or not?
If someone licenses an impersonator's voice and it gets very close to the real thing, that feels like an impossible situation for a court to settle and it should probably just be legal (if repugnant).
