Trash Talker

Enjoy a fun app built around phone calling your friends. The interface is a large switchboard of buttons that cause a text-to-speech voice to speak the phrases. You can add your own phrases, record the latest phrase to file and install more voices (through Windows) to add more fun. Note that the app doesn't directly support calls, you simply have to route your audio in to your phone's mic for this.

This is a remake of the app known as STP, which adds more refined functionality and smoother operation, but remains true to the original concept.
