Ok, from a quick look through the wiki page it looks like we have the
The api needs a method to set the language, windows/mac/linux have api
to get a language list, but android doesn't.
The api needs a way to set the voice parameters, this includes but
isn't limited to gender, speed, pitch, volume, id (module on linux?).
In some (all?) platforms the language is another voice parameter also.
I see this working one of two ways (jovie had/has both, but I think we
should pick one and stick to it)
1. The api has a voice type (QTextToSpeechVoice) and the api has
get/set methods of these objects which contain all the other
2. The api has getters/setters for all properties and the
QTextToSpeechVoice type is removed, so setRate, setPitch, setVolume,
setGender, setId, etc.
Either way we should have appropriate qWarning messages on each
platform for the voice parameters that aren't supported on that
platform. Also, I'm leaning towards solution 1 since that way we could
extend the api easily later by adding properties to the
QTextToSpeechVoice class itself if needed and it more closely matches
the backends from what I've seen.
Also, I had imagined that rather than having spd default configuration
api in qtspeech itself that we could/would have jovie become a kcm to
wrap spd-conf itself. Maybe another tool could be added like qtconfig
too, not sure, for those not wanting for whatever reason to run a kcm
or spd-conf itself.
