Sure :)

These are the interesting parts of it:

So they provide their own interface instead of the standard serial
interface... I however guess they didn't build their own chip. Do you
perhaps have some technical manual which could tell which chip they
used, so we can teach the linux driver for it how to deal with the
synthesizer? Or perhaps some contact at the manufacturer which could
provide information?

So you do have the USB support in speakup. It's just the linux USB
drivers which don't know about the Triple-talk.
