Many of the smart speakers use microphone arrays. Amazon Echo has 7 in its array, showing that arrays are feasible in $150 smart speakers (Echo 3rd Gen is $100). Even the Echo Dot has 4. Google seems a little lacking in this respect--Google Home only had 2 it seems.
These devices then should be able to recognize that a sound they hear, like glass breaking, is actually coming from more that one distinct source, and the directions of those sources. It should also be able to recognize that it often hears duplicated sounds from those same directions, and infer that this is where speakers for the user's home theater are.
It would be a neat feature, though, if these smart speakers recognized the sounds that home theaters calibration systems such as Audyssey use so after you get a smart speaker, you could tell you A/V receiver to run through calibration. The smart speaker could then recognize that and learn about all of your home theater speakers.
