Orca new user with a few questions

[Jason Fayre <jfayre cocenter org>]

Hello everyone,
I have just installed Ubuntu Edgy Knott 1 on a system and I have Orca 
working with speech and braille.  So far, it seems to work fairly well. 
 I have a couple questions though.
1.  Is anyone working on a Cepstral Swift driver for gnome-speech?
2.  Can I use an external synthesizer with Orca, such as a Dectalk Express?
3.  Is the version of Open Office that is included in Edgy sufficient 
for accessibility, or should I go and get one of the recent snapshots?
4.  Is there a version of Firefox and evolution that I can get that will 
work better with Orca?

Well, I guess that was more than a couple questions, but any help would 
be appreciated!
