I know Phones dont listen but....

I appreciate the links, but these are all about how to efficiently process an audio sample for a signal of choice.
My question is, how often is audio sampled from the vicinity to allow such processing to happen.

Today I decided to check with a couple of local insurance agencies to see if I could get my family's current coverage any cheaper. I never searched for this specific topic, only for contact info to reach out to a couple of agencies. Then I made two phone calls, sent two emails via the Gmail app including my current policies declaration pages, and I received one text message from an insurance agency. Now my news stream is flooded with ads for comparing insurance rates and changing companies.

more than likely it was the two emails in the gmail app

I mean, I know everyone says it’s impossible for phones to be listening, but I feel like there are just too many examples for that to be the case. My friend was looking for something for our other friends birthday. Her husband suggested opening instagram and talking about the thing she was looking for, describing the specific jacket, saying the company started with an “A.” Minutes later, she got the ad for the jacket she was looking for.
When I was driving with some people from work, we were talking about daddy Yankee, and his song “gasolina.” We were using maps to navigate home from an away job. On our route, suddenly there were multiple waypoints suggested on our map, “estaciones de gasolina.” We were speaking English, the person whose phone it was doesn’t speak Spanish.
If they’re not listening, how could these things be possible?

I hope they listen to me absolutely ripping ass. The idea that some corporate lackey who is noting what I say to feed me targeted ads just has his eardrums blown out by my booty thunder on a regular basis warms my heart.

I was watching a recording of Jeopardy (captured via antenna) on my private media server. This was not a recording of a recent episode. One of the answers was a band I've never heard of. The next day Pandora played a song by that band.

Do not forget phones give location/profile data and can easily extrapolate the people you're meeting. It doesn't even need GPS, just need to see which wifi networks are available and compare.
More than listening, it deduces things based on the fingerprints people leave.

You can't with an OS full controlled by Google or Apple. You can only alleviate the problem, using alternatives, such as LinageOS, Ubuntu Mobile, de-googled Android or another distro, but only if you have root access.

One day I had my phone charging on the same table I was measuring a liquid from two glass dropper bottles. The phone heard me shaking the bottles, clinking the glass pipettes, and dropping the liquid into water. I’ve never ever talked about dropper bottles as I didn’t know what they are called before this incident. I had bought the liquids with their bottles about a month before, and I’ve only ever referred to them by the brand name of the liquid.
My Quora feed 20 minutes later:
“What are the advantages of using dropper bottles in chemical processes?” -

Your stumbling block seemed to be that you didn't understand how it was possible, so I was trying to explain that, but I may have done a poor job of emphasizing why the technique I described matters. When you said this in a previous comment:
I do think that they’re not just throwing away the other fish, but putting them into specific baskets.
That was a misunderstanding of how the technology works. With a keyword spotter (KWS), which all smartphone assistants use to detect their activation phrases, they they aren't catching any "other fish" in the first place, so there's nothing to put into "specific baskets".
To borrow your analogy of catching fish, a full speech detection model is like casting a large net and dragging it behind a ship, catching absolutely everything and identifying all the fish/words so you can do things with them. Relative to a KWS, it's very energy intensive and catches everything. One is not likely to spend that amount of energy just to throw back most of the fish. Smart TVs, cars, Alexa, they can all potentially use this method continuously because the energy usage from constantly listening with a full model is not an issue. For those devices, your concern that they might put everything other than the keyword into different baskets is perfectly valid.
A smartphone, to save battery, will be using a KWS, which is like baiting a trap with pheromones only released by a specific species of fish. When those fish happen to swim nearby, they smell the pheromones and go into the trap. You check the trap periodically, and when you find the fish in there, you pull them out with a very small net. You've expended far less effort to catch only the fish you care about without catching anything else.
To use yet another analogy, a KWS is like a tourist in a foreign country where they don't know the local language and they've gotten separated from their guide. They try to ask locals for help but they can't understand anything, until a local says the name of the tour group, which the tourist recognizes, and is able to follow that person back to their group. That's exactly what a KWS system experiences, it hears complete nonsense and gibberish until the key phrase pops out of the noise, which they understand clearly.
This is what we mean when we say that yes, your phone is listening constantly for the keyword, but the part that's listening cannot transcribe your conversations until you or someone says the keyword that wakes up the full assistant.
My question is, how often is audio sampled from the vicinity to allow such processing to happen.
Given the near-immediate response of “Hey Google”, I would guess once or twice a second.
Yes, KWS systems generally keep a rolling buffer of audio a few seconds long, and scan it a few times a second to see if it contains the key phrase.

Boom
