Sounds like it's something more suited to building speech systems than being a completed one. I could hear the Speak & Spell effect in it though.
BTW, I wanted to point out, on that Pink Trombone thing, if you change the shape of something and keep the left mouse button held down while clicking the right mouse button, you can lock a deformation in place. That means you can input more than one deformation.
Haven't got a clue how to remove them though!
