1. For our skill, the word "Cancel" doesn't seem to trigger the CancelIntent. I've tried extending the utterance list for CancelIntent from the Skill Builder Beta to include "Cancel" as a sample utterance, but that still doesn't work work. Whether or not it's added to the list, saying it just makes the device beep, and keeps the conversation session alive.
(I want to mention that we have actually defined "Cancel" as a slot value that we're using for one custom intent, which is important for how that conversation session is supposed to be spoken.)
2. As a separate but related issue: our conversations have Alexa saying "What else can I help you with?" at the end of nearly every message, so we wanted certain extra phrases to trigger a StopIntent.
We're trying to extend the StopIntent utterance list using the phrases "That's it", "That's all", "Nothing", and "Nothing else". "That's all" and "Nothing else" work, but "That's it" and "Nothing" don't.
"That's it" / "Nothing" also end up making the device beep, and keep the conversation session alive.
(These aren't custom slot values anywhere.)
3. "Exit" and "Quit" cause a complete shutdown of a conversation - I haven't figured out how to be able to send a session end message for these cases. Adding them to the StopIntent utterance list also doesn't work.
So we have five phrases (Cancel, That's it, Nothing, Exit, and Quit) that we can't seem to really actually use as intent utterances. Do all of these fall under some list of key phrases that we're not allowed to use?
