Are Sound Sensors a thing?

Alexa has a sound detection public preview, and it can listen for Beeping Appliance as one of the things.
Not sure if that would work with Alarms.
Actually its not available in my region but Alexa Guard does listen for Alarms.

I've tried it and had basically zero luck getting it to work. It would be nice if you could put the Echo device into "listening mode" and trigger the alarm, so the device could send the recording up to the cloud and get it added as a viable trigger.
