My speech-dispatcher was installed as a Debian package, so the
configuration is in /etc/speech-dispatcher. Here is the line from

Here are my AddModule lines from speechd.conf:
AddModule "flite" "sd_flite" "flite.conf" "/var/log/speech-dispatcher/flite.log"
#AddModule "festival" "sd_festival" "festival.conf" "/var/log/speech-dispatcher/festival.log"

#AddModule "espeak" "sd_espeak" "espeak.conf" "/var/log/speech-dispatcher/espeak.log"
#AddModule "epos-generic" "sd_generic" "epos-generic.conf" "/var/log/speech-dispatcher/epos.log"

My kernel is 2.6.21, and cat /proc/asound/version shows this:
Advanced Linux Sound Architecture Driver Version 1.0.14rc3 (Wed Mar 14 07:25:50 2007 UTC).

Speech-dispatcher is started during system startup in
/etc/init.d/speech-dispatcher, and if it is running, then the madplay
program finds /dev/dsp blocked, but the play command has no problem.
Stopping speech-dispatcher allows madplay to use the /dev/dsp device,
and of course play can do so as well.
Other applications that find /dev/dsp blocked include festival and
I have been using speech-dispatcher 0.6.2 from the Debian package along
with espeak 1.26, also from the Debian package, for quite some time
without these problems.
Any more information I can offer, please let me know.
