You might have to do a little digging around on those links. There are some that will work with a variety of messenger programs and not all are free. I've never used anything like that, so I have no recommendations.

But that is the search you need. It's called voice masking.

Well it's doable on Ventrilo and multiple voice over IP proggies so im guessing theres plenty out there for messengers. I know some proggies like these ones:

are supposed to work fine otherwise ive heard thatsome webcams also have the option (webcams with built in mics) anyways.

You can read a book "How to talk with difference voice in MSN ".

I had use it to do this.
