Speech-dispatcher, Festival and Flite

[Hermann]

Hi,
this evening I tried to add Festival and Flite to my SD modules.
In both cases I failed. Festival wants the Festival server, that's 
installed on my Ubuntu machine. But when I start SD, I get the message 
that a file named speech-dispatcher.scm was not found. Which file? Where 
to get or how to create?
Flite runs over OSS, but for better results it was recommended to 
install NAS. Since I don't know the program I didn't install. Is it 
useful, and is it easy to handle? I could use Flite with OSS, but that 
device blocks other sound applications, such as music and video players, 
so I don't like it.
Any tips and hints?
Hermann
