TTS libraries can now be used in default Mingw-w64 environments.
- Removes reference to sapiddk.h which isn't used and isn't in Mingw-w64
- Defines guids whose symbols are missing from Mingw-w64
- Restores TTS detection to configure script
Similarly as on linux, there isn't enough control of the speech
queue to properly implement INTERRUPT_NO_REPEAT. So since this
commit we use our own queuing and use SAPI to speak each speech.
This is done outside the main thread.
* Delete multiple empty rows
* Make getVolume non-virtual and leave just the implementation
in base class
* Resolve warning about signed / unsigned comparison in
gui-manager
* Clear availableVoices when updating voices on linux
* By default set language to transMan language on windows
(if the transMan is available)
* Remove freeVoices method from Windows ttsMan, it isn't needed
anymore
Voice is changed when changing language on windows, so when poping
state, the voice, that should get set has to be saved before
changing the language.
The speech shouldn't continue when changing state, so it is stopped
in pushState and popState.
Main changes are:
* Save age information about each voice
* Remove Sample TTS Voice from available voices, because it
basicaly cannot speak.
* Stop speech after silently playing the test speech (the last
voice could be heard speaking after the volume got
restored to its original value)
* Remove voice data freeing from freeVoices, because it gets
freed automaticaly
The ScummVM was crashing because of an assert, when there was less
voices availaible, than what was set in the ConfMan.
Now the voice just falls back to 0th voice, if there are not
enough voices.
