#3 turns out to be complicated to do in practice, because the API Alexa exposes to allow third-party "skills" to handle voice commands requires them to be phrased in a pretty specific format that includes the name of the skill (see https://developer.amazon.com/public/solutions/alexa/alexa-sk...). Which is a big ask for a user in a high-stress emergency situation, especially if the skill is one they aren't going to have been routinely interacting with before then. (And a 911 type application is sort of the definition of an app the user will not be routinely interacting with.)

I tinkered a little bit with this idea when the Echo Dot came out, but these limitations more or less killed my interest in exploring the concept further.
