Low Speakup volume in Ubuntu?

I have managed to increase the volume in Speech-dispatcher and Espeak
with the normalize program in Slackware Linux.  The file
/etc/speech-dispatcher/modules/espeak-generic.conf contained these lines:

GenericExecuteSynth \
"echo \"$DATA\" | speak -w /tmp/espeak.wav -v $VOICE -s $RATE -a $VOLUME -p $PITCH --stdin && aplay /tmp/espeak.wav"

These lines can be modified to include normalize to add 10db of gain as follows:

GenericExecuteSynth \
"echo \"$DATA\" | speak -w /tmp/espeak.wav -v $VOICE -s $RATE -a $VOLUME -p $PITCH --stdin && \
/usr/bin/normalize -q -g 10db /tmp/espeak.wav ; /usr/bin/aplay /tmp/espeak.wav"

Edit carefully--the version of Speech Dispatcher you are running might be different from the one I am running.

HTH, and have a great day.

This is a little frustrating, but at least I've confirmed that the system works as intended for the most part.  I can modprobe speakup_sftsyn anyway.
