Some time horrible speech in Ubuntu 13.10 awailable Espeak and Speech-dispatcher

[Hammer Attila]

Hi,

My local system I resolved the wrote problem.
I downloaded the Espeak source package in Saucy, and removed 
/debian/patches/series file the sonic and Pulseaudio related patches.
My system I using since morning the modified Espeak package and not 
happened any distortion with Orca and Speech-dispatcher in Ubuntu Saucy. 
Previous day I first time removed only the sonic related patch without 
good luck.
Have chance only the Pulseaudio related patch producing the problem, but 
I choosed the safest way now my local system.
I attaching the two patches with I not applied my system when compiling 
Saucy awailable Espeak from source.
Luke, can you little look this patches to we known full sure what patch 
producing this distortion/fast speech related problem with some 
undeterminable situations?
Only sonic patch remove not solved my machine the experienced problems, 
but not tryed yet only remove the pulseaudio related patch and keep the 
sonic related patch.
If the sonic related patch absolute clean and good, I doing an another 
longer test the second combination.
Final, if we knowing what patch need absolute sure removing, I will be 
opening a report in Launchpad and attaching a debdiff.

Description: Trigger speech start on final chunk of write
 When espeak is used with pulseaudio, the last part of a line or other chunk
 is not spoken because pa_stream_trigger needs to get called to start
 speech.  This is called if the buffer is full and writes are not
 progressing.  However nothing calls this for the last part of what's
 being spoken.  The contract for wave_write on the portaudio side
 seems to start the stream, so do the same on pulse.
 This patch takes advantage of the fact that calling pulse_free twice
 in a row with no write causes a trigger.  An alternative but larger
 change would be to refactor that code out of pulse_free.
