Dear Developers,
Some time if Speech-dispatcher Espeak module active and Speech-dispatcher using Pulseaudio, the speech rate changing very fast rate, and this problem resulting distorted, not understandable speech quality.
Affected Ubuntu releases:
Ubuntu 13.10: Speech-dispatcher packaged version is 0.7
Ubuntu 14.04 development release: packaged Speech-dispatcher version is 0.8
Upstream git master branc speech-dispatcher version with affected too: Speech-dispatcher 0.8
In Ubuntu a11y list Luke wrote following issue:
"What fix is this exactly, and in what package? I am aware of audio issues with espeak and speech-dispatcher in 13.10, and its a combination of speech-dispatcher's pulseaudi ocode and pulseaudio itself. Speech-dispatcher is probably not using pulse as well as it could be, at the same time, pulse has had changes made that somtimes cause audio issues. I've tried following this up with upstream, and some work has been done to try and look into this, but it seems we're not there yet. I need to try git master of pulse myself to see if things are resolved.

Don't surprise the modified package components, I using now Speech-dispatcher latest git master version.

This is a pulseaudio issue, that seems to be fixed in pulseaudio 5. However pulseaudio 5 will not be in trusty. I am going to take time to try and find the commit that fixes it, and see if it can be backported.
