I'm struggling with the certification, because stopping my intent after speaking the wakeword does not work. That's the relevant code snippets in the "LaunchRequest" handler:
return handler_input.response_builder \ .speak(speech_text) \ .set_should_end_session(False) \ .ask(ask_text) \ .response
According to the certification feedback it should be possible to say stop between the speech_text and ask_text (which is a few seconds later). However the stop nor cancelled intent does not get triggered. I also tried to add utterances "stop", "cancel", etc. to the prebuilt intent, but it still doesn't work.
How can I enable a user to cancel in between .speak and .ask?
