Hello,

the various ways of running Speech Dispatcher are
described in
http://www.freebsoft.org/doc/speechd/speech-dispatcher_9.html#SEC22

Even when running as a system-wide service, it is recommended
not to run Speech Dispatcher under root, but under some special
user like 'speech-dispatcher' who has only access to the appropriate
log/config/pid destinations and to the audio hardware for the security
reasons mentioned above. I think the Debian package for Speech
Dispatcher is a good example.

With regards,
Hynek Hanke
