When the user says an unrecognized response, e.g. "potato" or "turtle", Alexa doesn't call the fallback, but instead responds with a quick bloop only. The expected behavior is for Alexa to send a fallback intent to the lambda, after realizing that potato is not in any of my other intents. Alexa doesn't send anything to the lambda. How can I get Alexa to send a fallback intent when an unrecognized response is heard?
In regards to previous posts about it being a low confidence in ASR, the user very clearly states "potato" or "turtle" and Alexa recognizes it. In addition, when testing and typing in these words, the above described events happen. So it should not have to do with ASR being unable to generate text for the words.
