Well all the Pitch alteration things i've tried( FOR MAC, cause i have mac) create Warble.. so it makes it sound like  robot. 

I tried it with Garageband, and recently with a thing called VoiceTweaker.
They do good voices, add to that the fact that I also change my voice and i have made up some neat character voices. But they create warble .

I'm guessing there's better voice changing software for the PC cause most things are made for pc.
But anyways, that's why i'm happy i got Female voice talent to help me.
