Re: Fixing gnome-speech

Speech-dispatcher in general works well with screen readers. I am using it with its generic module as I am writing this email. It stops speech by killing the command-line program that is executed by the generic module. This works better than one would expect. When testing Orca or Gnopernicus, I these days always use the speech-dispatcher driver in gnome-speech to drive a synth through the generic speech-dispatcher module. As I recall, Swift also has some command-line program that can say a phrase or two, so it should be relativly easy to make that work also.

Hi Willem:

That's good news about the DECTalk and TTSynth support.  If we could get
a Cepstral/Swift module as well, I think we'd have the major synths
covered.  Perhaps the gnome-speech FreeTTS code could be ported to the
SpeechDispatcher API someday, to give us two free engines (especially
now that Java licensing is more acceptable to free distros).

I suspect the 'generic module' may not work well for screen readers
because of the need for speech markers or at least "end of speech"
notification, but it's still useful for some things of course.

regards

Bill

Speech-dispatcher is very stable, even when using an unstable generic
synthesizer.
Although the generic module has some limits, in practice, it works well.

Does Speech Dispatcher support something other than Festival now?
Gnome-speech has support for quite a few speech engines including some
commercial ones with much clearer speech.  Unfortunately one of the best
values and clearest sounding options, 'Theta' from Cepstral, has been
obsoleted by the new Cepstral Swift engine; we need someone to port the
Theta support over the Cepstral.

While free voices and engines are really important, for some users
clarity of speech is paramount, so it's important to have support for at
least the less expensive non-free TTS engines.

I don't have any objection to using Speech Dispatcher as a common
back-end, if there are more resources available to keep it up to date
compared to gnome-speech.  But we shouldn't move over entirely until we
have comparable driver support.  One area where Speech Dispatcher seems
to be ahead is in support for non-English Festival voices, but I think
that testing is the only impediment to using the non-Engish voices in
gnome-speech as well (the Festival API is the same in either case).

 this

may be essential for some people and the Orca -> Gnome Speech -> Speech
Dispatcher -> synthesizer aproach has inherent problems.  This might
solve your problem too.

Please, see also the common "TTS API" draft at
http://www.freebsoft.org/tts-api.  This is a common effort of Free
Desktop and FSG.


Very very good idea.
Unfortunately, gnome-speech was not very stable, sometimes speech
randomly stops.
And it's true that it will optimize the speech chain. orca -> gnome
speech -> speech-dispatcher -> synthesis was quite long :) And so, it
must be nearly impossible to debug it.

So thanks very much Tomas for this work !
