Max speech munged in Pd

Still at the point of being a tech demo, but my latest text-to-screech project has moved forward a little. Here you can see speech sounds controlled by Max 5 piped into PureData. In Pd, I'm using some old tricks with the 'freeze' function in freeverb plus some pitch shifting to further play with the sound. As a potentially interesting wrinkle, the effects in Pd are turned on and off by the words typed in Max: 'reverb', 'freeze' etc.

Hmm. Where to go next?
