If so, I suspect they’ll be okay in a court of law — having a voice similar to a celebrity isn’t illegal.
It’ll likely cheese off actors and performers though.

"when voice is sufficient indicia of a celebrity's identity, the right of publicity protects against its imitation for commercial purposes without the celebrity's consent."
If they had just screened a bunch of voice actors and chosen the same one no one would care (legally or otherwise).
