Please have a look to paplay code.
Using espeak-genric driver in speech-dispatcher through pulseaudio (with
paplay).
produces very well working output.
I am using the following command in espeak-generic.conf

GenericExecuteSynth \
"echo \"$DATA\" |\
espeak --stdout -v $VOICE -s $RATE -a $VOLUME -p $PITCH $PUNCT --stdin |\
paplay -"
The command pipes espeak output through paplay and doesn't need a
temporary wavfile for playback.
The test shows that the problem must be in speech-dispatcher pulseaudio
code (not in pulseaudio).
The generic stuff works as expected fast, reliiable and with low
latency.
I am using this since 6 weeks.
The solution was tested with ubuntu karmic kernel as well (works).
