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.

Title:
Some time Speech-dispatcher speech rate changing faster, this is
resulting distorted speech output when Espeak module is used
Status in “pulseaudio” package in Ubuntu:
In Progress
Bug description:
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.
Luke"
Don't surprise the modified package components, I using now Speech-dispatcher
latest git master version.
