How to pause audio.connecttospeech() .. and how to stop (clear buffer) ?

[kaloprojects]

Maybe a dummy question (sorry), just want to understand 'how to 'stop' the I2C Audio (with keeping audio-loop() in main loop).
2 use cases (just edited to make it more clear)

Usecase 1 (stop): Background: I want to use audio.connecttospeech( text1 ) .. and being able to stop text1 audio via a button (stop and erase, not pause) because i want force silence, would allow me to send a 2nd text immidiatly next. Do i understand correctly that i could call audio.resetBuffer() to stop before I am calling a new audio.connecttospeech( with text2 ) ?

And use case 2 (pause): Want to hold audio on pause via another button (pause button of spoken text) and proceed on release.
Thx !

found it, each new audio.connecttospeech clears buffer itself, which is perfect (for STOP), and pause can be realized with pausing audio.loop() in main loop. All fine, thread can be closed.
