If anybody is interested, back in about 2013 I wrote a library and a new
version of espeakup to use it.
Look in:
https://github.com/cromarty/ttsprojects
Look in:
raspberry-pi/libpipcmrender
and:
raspberry-pi/piespeakup2
The library uses OpenMAX to directly render speech on the GPU, thus
avoiding ALSA.
I did a podcast on Hacker Public Radio demonstrating how much better
speakup was on the Pi using this library.

hello. Just out of curiosity, is there a way to get the audio system to flush its buffer
before it finishes speaking the current buffer? I know when I worked on getting eflite working
on my systems many years ago, the speech engine was calling the drain ioctl rather than the
flush ioctl when the stop speech command was issued to it. Changing the flite engine so it
could distinguish between drain and flush fixed the problem and made things very responsive
without having to tweak buffer sizes.
