Pretty cool! I tried it with this small dialogue, and then edited together two voices in Reaper from the downloads:

Bob: “Hello, John.”

John: “Oh, hello there, Bob.”

Bob: “Yes, hello. It's what I said. Why do you keep repeating what I say, John?”

John: “I didn't repeat you! I merely said hello, you dimwit!”

Bob: “There you go, being condescending again. Fuck you!”

John: “What? You're the one who started it!”

Try it yourself, or write something different. Either way, good fun!
