Need a voice changing software
 

I need a software to edit my voice recordings. I'm making a wow movie and i don't want to use (or like) my own voice.

is there anything out there than can change the pitch or tone or a sound file? i remember creative soundcards offer voice changers, i basically want something like that.

You could try checking out Vocaloid. While its not a voice-changer, I hear it has well done text-to-audio capabilities.
I guess there is also Celemony's Melodyne.
But those are more music oriented solutions.

There is another program that I came across called MorphVox. You could check that out too.
