What happens when you let a computer talk to itself? Or when different voice software play a game of Telephone?

This toy lets you queue up any number of supported Text-To-Speech and Speech-To-Text softwares in succession and see the hilarious results. It also provides a simple plug-in interface to hook up your own Text-To-Speech or Speech-To-Text software.
