The main problem with the ad-companies-are-listening-to-you theory is that audio processing is very power hungry. Running an ASR model locally would eat up a ton of power. Just doing wakeword detection (where you're only listening for a specific phrase like "Hey Siri") generally requires a dedicated specialized chip so as to not impact power consumption too much.

Same problem if they were surreptitiously streaming audio to their servers. You would see it from the outgoing packets and streaming that amount of data would also be fairly expensive.

What if it's not audio processing real time?

Some voice codecs get their rate down to 2-3kbps. Maybe it could store and forward with content loads without raising flags?

Just spit balling here.
