Voice Changer app (real time voice changing, not post processing)

I want to tweak my voice when streaming (podcast or video)... sometimes make it deeper, sometimes make it higher.

Lots of free apps that apparently do this. See list below.

But nothing I could find that's portable. I need a portable app...

Got any recos?
