Summary: We have had this in desktop for several years now. This introduces
WebSpeech API synthesis support in Fennec and GeckoView.
Bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1463496
Standard:
https://w3c.github.io/speech-api/webspeechapi.html#tts-section
Target release: Firefox 62
Preference: media.webspeech.synth.enabled. It is currently only enabled on
desktop platforms. The intention here is to enable it on Android.
Concerns: Our integration test coverage is pretty limited for actual
platform speech synthesis. So my hope is to uncover glaring bugs in the
pre-release cycle.
Eitan.
