I'm curious how the legal stuff will play out. They definitely did something that feels wrong. On the other hand, some people make their living impersonating famous actors, voice and all.

And what is the range of "similar enough to", specially for human perception, and I don't mean what our senses get, but our brain does. At least with vision there is a lot fill-in-the-blanks and more processes going on all the time.

I don't mean that it is what it really happened, or the real intentions in this, but setting legal precedents for something that may be pretty fuzzy in real life is dangerous.

That would've made a better case if they hadn't tried to hire ScarJo for this.

This looks like: 1. They wanted ScarJo's voice 2. She said 'No' 3. They then proceeded to ask themselves the question you're asking. "How many different voices are there?"

Alternatively they said "well, we didn't use Her voice."
