driving a serial synthesizer through speech-dispatcher

[Gregory Nowak]

I forgot to add one more thing. The idea of using speechd-up to let
both speakup and gnome-speech use speech-dispatcher is not a bad
one. However, speechd-up was written as a proof of concept, and
doesn't implement full functionality like espeakup does. I suppose I
could look at that code too, and polish it to the level of espeakup,
but I frankly don't feel like it. A different module to drive a
different synth would still be required if speakup didn't do the heavy
lifting, instead of writing just one module.
