The fact that it has to analyze audio makes me wonder if anybody is trying to standardize broadcasting of local emergency signals. For example, a standardized way to broadcast a fire alarm over WiFi or Bluetooth. There's more than local humans that could be alerted. Local systems could use it a cue to shutdown and remote service providers could be alerted that they have to do something.
A specific use case I was thinking of is some local hotels that my company does IT for. Hotels have lots of third party systems embedded locally and service providers doing stuff for them. If the fire alarm sounds, I'm sure they would love to know about it so they can react faster, either for assisting with the immediate crisis or facilitating the recovery. As far as I can tell, the fire detection/alarm systems are stovepipes that don't tell any other systems (other than 911) what is going on.
