If you could add a feature to alter your voice so that anything you said sounded like a specific character, who would you want to sound like?
I've got several choices. Don Adams (Maxwell Smart) "I asked you not to tell me that" and Foghorn Leghorn "Any fool knows that adding a half-naught to a half-naught gives a full-naught. Son, you've got to start paying attention"
(On the bright side, making everyone sound like a character couldn't really hurt the use of VoIP communications in games, could it?)
Logic, my dear, merely enables one to be wrong with great authority.
