I’m aware of that, but we seem to get get distracted from the main point. In the case of OpenAI versus “Her” (i.e. Them launching a similar product, and referencing the film), I think it’s the owners of the Her IP that should have a right to complain. Not an actress that was in it, and whose voice is similar to it. According to the article, there were 2 well-known actresses whose vice matched even better. Should they take action as well?
All of this is under the assumption that they didn’t actual train on her voice - which does seem likely.
