Voice Modulation Software

Does anyone know of a good program that I can buy (or is free) that can modulate my voice. I want to prerecord some things and I need to be able to make my voice sound like a couple of different people (men/women/children)

I've looked online and i've found a few (i.e. morphvov) but all the ones i've found seem to suck. I'll record my voice and it sounds nothing like what it should. Young girl sounds like chipmunk, old woman sounds like a deamon, child just gets high pitched horrid noise. (these are just examples)

I dont know if i have to use them in a freaking studio with sound proofing or what but none of the ones i've DLed or bought so far have given me very promising results.

I just want to be able to hook up my headset/mic and say a sentence and the program change it so it doesnt sound like i'm saying it. (and i would like to save these recordings to a file if possible)

Thanks for any help you can give me

Dell webcam comes with a very good one. Don't know if you can d/l it free with a search about the Dell support website - maybe?

 

I have a Gateway 6860fx so it will probably not work, but i'll give a look around to see.

Any one have anything else?
