classic TMNT voice transformation software?

[lilonardo]

Does anyone know if/where I can download software for my computer that will allow me to transform my voice when I am using the "sound recorder" program on my windows computer so I can sound just like any of the 6 turtles (Leonardo (classic voice) , Donatello (classic voice) , Raphael (classic voice) , Michelangelo (classic voice) , Zach and Venus) and so I can sound just like other turtles characters? I am working on an interactive cartoon videogame for the PC called "Teenage mutant ninja turtles fusion" of which takes elements from the original cartoon, the next mutation and the new cartoon and fusing them all in to one interactive cartoon.
