Home automation is the residential extension of building automation.
It is automation of the home, housework or household activity.
Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Something that's relatively easy for an advertising giant like Google to do is add an audio signature to video advertisements to get a sense of when ads are being viewed. The resulting data (probably a uuid and timestamp) would be small and could go with the next prompt or perhaps firmware update.
I definitely agree the concern about every conversation being uploaded is nonsense though. It's too much data for them to store and process locally and wait for a window to upload in discreetly.
I'm legit surprised more isn't being done with ultrasonics/infrasonics in the exact areas you describe.
There was one project I worked on to help spec-out and design a device location system at a hospital and one of the solutions we vetted actually used low power ultrasonic exciters producing known and unique patterns paired with tiny little microphone equipped pucks with just enough smarts to record the relative volumes of multiple exciters and send that via radio to a central server along with its own unique ID to be used for triangulation. Ended up being too expensive for us and we went with something based on a combination of BLE and LoRA, but holy shit was the sound based stuff cool (and wouldn't crowd the radio environment nearly so much, which can be a big deal in ultra dense environments like a hospital.)
Thanks for your input. These are very valid points.
