Question about speech-dispatcher inclusion

[Henrik Nilsen Omma]

Hi,

An interesting post that seems to have gone unanswered. I'm not the most 
qualified to write about speech drivers, but I'll give my view.

We opted to go with the gnome-speech option because of some limitations 
in speech-dispacher and because the Orca speech-dispacher driver was 
still in alpha when we made the decision. We certainly did not want the 
Orca -> Gnome-speec -> speech-dispatcher -> espeak chain that some 
people were using at the time.

How are you running it now, with the Orca SD driver? What would be the 
advantage of writing a direct espeak driver for Orca? (I ask because I 
don't know, not rhetorically)

I generally a fan of the idea of speech-dispatcher, the flexibility it 
gives. But it's fair to ask if we need the extra layer if we can have 
direct drivers for espeak and festival? These will after all be the 
mainstay of our offering.
