Kind of, not in that there is a binary “celebrity/not-celebrity” divide, but the interest protected and the potential for damages from violating them are associated with the kind of public commercial exposure that is associated with celebrity.
So if you hire a voice actor that naturally sounds like a celebrity then you should be safe from any legal action. Otherwise they could sue each other.
Look up the concept of mens rea - the intent matters. If you hire somebody because you want a look/voice-alike that is legally distinct from hiring somebody who happens to have a certain voice.
