people are allowed to sound like other people. But if you go to actor 1 and say we want to use your voice for our product, and then they say no, and then you go to actor 2 and tell them I want you to sound like actor 1 for our product, and then you release a statement hey you know that popular movie by actor 1 that just used their voice in a context extremely reminiscent of our product?!? Well, listen to what we got: (actor 2 voice presented)
on edit: assuming that reports I am reading that the actress used for the voicework claimed not to have been instructed to sound like Her vocal work it sounds like it is probably not likely that a suit would be successful.
