No worries, the concept intrigues me. That 2nd link covers a markup language using xml to customize everything with how tts pronounces stuff. Probably more that's needed but it looks idea. Unfortunately as I soon found out the standard html5 tts doesn't support it.
The most I've found is a js lib that does tts and supports that markup language. The only issue is I find it sounds like garbage compared to most other engines.
I didn't look but if there's a tts plugin for android export it may support that markup language. To use it should just be a matter of using the xml text when specifying what should be said.
