You install the app and connect a mic. Part of the initial config of the program will be the program "learning" how you speak. Just set up something similar for my wife. Pretty straight-forward. Have fun!
OK that's what I thought. Can you use any microphone or do you need a USB one? The laptop I'm going to be using it on I think has a connector for a mic but I think I might want to go USB just to be on the safe side.
