This is a permissions bug in ALSA, it was reported and it has been fixed
since then. Basically only the first user to connect to dmix
could mix sound (if you are running speech-dispatcher, this will likely
be the user speech-dispatcher or root) and the other users got refused
You need to upgrade your libasound, I think.

This should not happen. The device is normally openned just before
playing a sound and closed just after the playing finished in OSS mode.
I just tested it.
I guess ALSA is still mixing in and giving you problems somehow.
Cannot it be that you are also loading flite output module and flite
loads ALSA and you run into that ALSA dmix permissions problem described
above? Try to disable all other modules than festival in speechd.conf
(option AddModule). (But this is just for curiosity, I recommend fixing
ALSA and using ALSA if possible.)
Have a nice day,
