I have often wondered if Siri is actually off when I set it to off. It is not as though I am running ps or top as root to check. A bit of a “trusting trust”.
At one point Google had highly specialized hardware that only listened for “ok Google”; that’s why you couldn’t (and AFAICT still can’t) change the wake word.
Things may have changed in the years since I learned that, but I suspect recognizing a bunch of words from an ever-changing list would still need to be done in software and require the phone’s CPU to run.
OTOH, the way Android phones recognize and songs for you is very much like what you described, so maybe there really is hardware already that can recognize a shitload of arbitrary sounds using practically no power.
Amazon, for example, has previously confirmed that it uses stuff people say (and do) with Alexa for targeted ads (Amazon has long claimed that it doesn’t sell customer data). But our devices are only expected to gather data on what we say when we ask them to listen to us.

That’s probably because you have no technical knowledge of voice recognition whatsoever.
Lots of people of Siri disabled entirely. My household included.

And you aren’t wrong, from page 2 of the article:
