Any time I try to teach my dogs to "speak" my smarty pants foster Dalmatian (who came pretrained when we found him) barks. One of my Pits will give his woo, woo, woo when I say "what are you doing white boy?!" and when someone walks into the room he's in. All 3 of my Pits think it's their time to "speak" when I ignore them though. So I guess if you want to teach a Pit Bull to speak, act like you are ingoring them and give them a treat when they tell you off with their smart mouths that they seem to be notorious for.
