Ever wanted to change the tone of your voice? MorphVOX Junior is a free voice changer software that is supposed to modify your voice to match your personality. If you so like, you can sound like a man, a woman, a midget, a robot and many other bizarre variations in between.
The program is optimized for online games, but obviously, the most fun you'll have with this is to make prank calls and wind-up your friends. The program can also send out some rather annoying high pitch screams and bizarrely, drum rolls.
This is great fun although there's not really much point to it. Perhaps if they had integrated it with a music making program or other editing software, it would have been much more useful. Still, you can save your voice modulations and then use the file in an external program.
