Modifying sound input

Anyone know a program that can modify sound input live? I need something that'll change my voice ...

i dont know about modifying sound input live, but i think i know something that can process sound from the microphone and output it to speakers.

try FLstudio and use the vst and fruity plugins on a mic input channel to distort your voice, or sony (bah) sound forge/adobe audition with their plugins if you want to record to disk.

in fact for the first method, try any program that supports mic input and vst plugins, there may be something less ott for what you're looking for.
