Re: [orca-list] Gnome-Speech Choppiness

[Mike Gorse <mgorse mgorse dhs org>]

Gnome-speech relies on the synth to output its own speech, so it will use 
alsa when used with espeak and Portaudio 19.

One way around it might be to modify the latency calculation in 
update_output_parameters() in wave.cpp in the espeak source.  There is an 
alternate suggested line that is commented out which should cause less 
glitches.  It may also make it take longer to silence speech; I'm not sure 
if that would be noticable, but it might be worth a try.  I haven't had 
any choppiness with espeak on this machine (I did with my old computer), 
but then I have a Core 2 Duo which probably masks the issue for me.
