I agree with @Hypnos3 here: https://github.com/Hypnos3/node-red-contrib-cast/issues/75#issuecomment-561871642
-
zlargon/google-tts uses Google Translate TTS, that is the synthetic voice currently used by Google in Google TRANSLATE web service. This voice is NOT controllable ( a part a minor/immo useless, speed setting ).
-
Google Text To Speech is the pay-per-usage Google Cloud Platform service. That's another story.
Now, some/small SSML features, as controlling pauses, could be possible, working on-top of zlargon/google-tts.
BTW, I'm working on https://github.com/solyarisoftware/jointts, a concatenative TTS experiment (that use this package, as an option). So by example, you can build speech, configuring that a BLANK correspond to some number of millisecond, A FULL_STOP to a bigger value of msecs, etc.
Nevertheless, I fair it's not worth implementing SSML for such a strict set of features. My two cents.
