I originally sent this directly to Willie, but I think it wouldn't hurt to also
send it to this list.

Hi Willie
Here are my top 5 things I would like to see happen:
1. gnome-speech/speech infrastructure.
2. gnome-panel (No point having it, if we can't access all of it)
3. TTS localization (Jonathan, the author of ESpeak would be the best person to
help here)
4. Rhythmbox. The computer is a jukebox these days, so lets make sure it works
well with a11y.
5. Evince. We need to be able to read PDFs etc. We shouldn't rely on Acrobat
Reader where at all possible.
My involvement in general for GNOME/Linux accessibility will be to keep Ubuntu
at the forefront of Linux Accessibility, and make sure the best tools are as
well integrated for users as possible, to make things as seemless as possible.
In light of the above list of attention items however, I feel I can help the
most with what I think is THE most important issue we need to resolve, and need
to resolve ASAP. Yep, you guessed it, speech. Firstly, there is the nice fact
that KDE will be coming online with accessibility some time in the coming
years, and they said early on, at least for use with the existing kde
accessibility tools, that they favoured speech-dispatcher's model. Secondly,
speech-dispatcher's model is flexible enough, that with some small
speech-dispatcher changes, third parties could easily build drivers for
synthesizers outside the speech-dispatcher source tree. This would especially
be useful for building support for proprietary speech synthesizers, and would
then make it easier for users to set up such synthesizers, without having to
rebuild speech-dispatcher, with the possible effect of screwing up their system.
There is also the changing face of audio infrastructure to be considered.
Luckily, just about all speech synthesizers support returning audio to the
calling application via a callback. Speech-dispatcher makes good use of this
with espeak, festival, flite, and ttsynth, and then can send the audio to one
of many audio outputs, such as OSS, NAS, ALSA, and recently, PulseAudio. At
this point, I am very much grappling with having to deal with what direction to
go for Ubuntu hardy, in relation to speech audio output, and PulseAudio. At
this stage, I am looking at wrapping the espeak-synthesis-driver gnome-speech
binary in a call to padsp, so that all OSS calls from espeak+portaudio v19 are
sent to PulseAudio. For next release, I will likely implement a
speech-dispatcher solution, as that is what users are asking for on the Ubuntu
accessibility lists.
if upstream could also support speech-dispatcher, that would be much
appreciated. I could then easily add scripts to the speech-dispatcher package
to allow for distributions to make use of speech-dispatcher per user session,
as that is how PulseAudio is being run, at least in Ubuntu. All this would be
possible, due to me now having speech-dispatcher CVS access.
In the longer term future, I would then write a nice GUI, to allow users to
more easily adjust speech-dispatcher's options, or even better, help in
implementing a hook into Orca, so that Orca users could directly alter
speech-dispatcher settings from clicking a button in the speech preferences
pain.
I would urge to consider my proposal, and my offer of help. Together with the
speech-dispatcher developers, we can sort out any remaining issues you think
exist, and move forward to using a completely GNOME abnostic framework for
speech output.
Thanks for your time.
