Honestly, I never really remember the names of people who are in movies or TV ot anything else anyway. I do, however, have mental ideas of how I want them to sound, and I know other writers do too. (Sparky from classy_cat18's A Doolittle of Pokemon has a New Yorker voice. Go figure.) I suppose one voice that could be used for a lot of characters could by Ray Romano, since he has such a distinctive voice. Or that one really whiny guy whose name I can never remember. See? Now do you see my problem?
EDIT: You know, you should really have a poll here, so we could get a better idea. After all, not everyone goes to the trouble to reply to these threads, but many writers at least answer the polls.
