Speech-dispatcher, etextRead activity and espeak

Last night I was able to do a yum install of speech-dispatcher and
speech-dispatcher-python in Fedora 10, so there is a good chance that
the same thing would work on the XO. I have not tried it. The install
will bring in festival-lite, at about 7 megabytes, which you shouldn't
need and may be able to uninstall later. (On the other hand, if it
works better than espeak it might be worth keeping). The configuration
files are in the /etc/speech-dispatcher directory and they look mostly
OK. They have an entry to load Festival which you should probably
comment out since you won't have Festival installed. Unfortunately,
when I tried starting it up with this command:
it complained about ALSA not being able to connect to the sound device
because of some issue with Pulse-Audio. It sounds kind of like the
problem described here:
There is a page on the OLPC Wiki that mentions speech-dispatcher:
This page is out of date and it incorrectly suggests setting up
espeak-generic, which does NOT support the callbacks needed for Karaoke
highlighting. If I can figure out how to get SD working with Fedora 10
or the XO I will update this page. I'll also update the page for Read
Etexts. Until then just be aware it's wrong.
If you want to have a crack at solving this yourself, please go ahead.
I don't have any special expertise for installing SD.
