I asked about this on the Ubuntu Accessibility list, and got this
answer from Luke Yelavich:

I have used orca with speech-dispatcher via gnome-speech, but not with 
espeak. It is to say the least, very clunky. There is a speech output 
module under development for orca for interfacing directly with 
speech-dispatcher, but it is still very much in the early stages.

What would actually be better, is to have a module written for 
speech-dispatcher to interface with the espeak shared library, rather 
than call the command-line utility all the time. Personally, I feel 
gnome-speech needs to be removed, and speech-dispatcher should be the 
speech back-end of choice.

Espeak will very likely be a synthesizer that will be used for various 
tasks in the next release of Ubuntu, such as spoken boot, 
https://wiki.ubuntu.com/SpokenBoot.

I intend to get the newest version fo espeak packaged in the next few 
days.
