voice language changer portable

hello, i would like for a program like this to be made so i can host my sc games in several different languages by firstly changing my and my friends' previous voice overs from english to anything else. this will probably get myself a little noticed if other people can understand what's going on when it's explained in their type of language, you know? i would be very grateful if a program like this was made for me to use as well as everyone else.
