Suppose I'm trying to create an indy CGI movie. Obviously, I can't afford to hire an entire cast of voice acting talent. The few voice actors I have (namely ... me myself and I) need to have their voices manipulated so that they SOUND like somebody different when they really aren't.
I think there was an episode of the Rugrats that involved a device like this. Angelica used it to order lots of junk food by making her voice sound like an adult's.
Is there any software out there - preferably a free license - that let's me do that?
