KF How to get Fleshpound voice?

Hi guys. I wonder how can I get myeslf sound like a Fleshpound. I was having fun with some programs and I changed my voice for example to GLaDOS from Portal series. But the Fleshpound voice is the best, especially NutPound one. I would love to get synthesizer or similar thing that would let me speak this voice on a regular basis. Can someone tell me how to pitch the voice?

Thanks in advance!

Greetings!
