Well they might do it with AI, there are however some issues, constantly running sounds through ML models is power hungry which is as far as i know why devices such as these optimize a lot for commands prompts such as "OK google" which is when the ML loop actually starts.

On the other smoke alarm sound is very easy to detect with classical methods so might be extremely cheap to run it without any ML.

How power hungry is it actually? I'd only have to run it on the big model if a pretty dumb model thinks that the voice is even in the audio stream.
