> There is so much time spent “debunking” audio recordings being shared
Not really. 99% of the time it's someone claiming that it happens.
And it's always an anecdote, never clear proof that it happened. Let alone that it happened because of the audio and not web activity. And that the conversation was actually the cause for the ad and not the other way around.
Is it technically possible? Sure. But if so many people are so certain that it definitely happens, why didn't dozens of people already prove it with a fresh Google/Apple account and phone?
I observed a clean experiment that showed a friend’s Google Pixel phone listening to us and adjusting news stories on Google app’s home screen.
However:
— IIRC the phone was unlocked,
— this only affected the news feed, and
— this was 5–6 years ago.
We 1) noted how Google app shows some selection of news after opening, 2) talked clearly for a minute about a very random and conspicuous topic in presence of the unlocked phone, and 3) demonstrated that the Google app showing an article relevant to the topic within a few minutes. The article was a few days old, too, so it was clearly boosted out of more recent stories.
The only reason it could be something other than the phone microphone is if I was misled by my friend steering us towards a predefined topic. However, that would require some extensive preparation to rule out the story appearing in the first step and would be very atypical for that person.
I recall seeing an article about Google admitting this and changing their policy to stop, but can’t seem to find it now. I imagine it was bad publicity, though to my friend it was a feature to see personalized content.
This was a coincidence.
That’s why it’s something you observed one time 5-6 years ago, not something that happens repeatedly in a testable way.
Isn’t it more likely it’s not a coincidence though?

Here is an example that just happened today. I talked to my partner about me going to a city directly (via one state) or indirectly (via another state). All I said was "so you want me to go directly to X".
Boom, Illinois tourism ad shows up the next time I hit the internet. Scary thing is I didn't even say the state name, just the destination, and SOMETHING calculated that Illinois is in the middle.
This stuff has now happened far too many times in the last 10 years of my life, it is simply implausible to call it coincidence at this point. You are being listened to by your phone.
Ad firms have no ethical boundaries, and have lied about their data collection over and over.
What is really frightening is that if the ad companies know everything about you, then multiple state actors also know everything about you.
Confirmation bias at its finest
Why would that be even be a good targeted ad? Its simpler and more profitable to show you ads about a place you actually plan to go to..
> You are being listened to by your phone.
This would simply eat the battery immediately, it's simply not feasible and given all the other, cheap tracking it wouldn't even be beneficial.
Not in 2025. I often record long duration meetings and working sessions with iOS voice memos. There’s no noticeable impact.
You could easily record and do a fast voice transcription to gather keywords from a hardware perspective.

It’s never packet captures, reverse engineering of the app, or one of the tens of thousands of employees working for these companies blowing the whistle.
Nobody can even show that their phone app is using background CPU when they talk, utilizing the microphone, or sending packets from that app. All of which are in reach for anyone with Android and some basic skills.
It’s always an anecdote about someone who said something out loud and then saw ad for it later. That’s it. That’s the entire basis for the conspiracy. Yet it persists.
It’s a very good litmus test for people who don’t understand technology as well as they claim to.
On the other hand it might point to something more serious, that the level of tracking Facebook and Google use lets them loosely predict what you are going to think about.
So maybe the microphones are safe and pristine, but we should be worried and appalled the same as if they were actually listening.
I like to think about it sorta thermodynamically: consider your behaviour under the blurred lens of interests, what you buy, what you read, how you react to news, etc, in this model humana have, let's say, n bits of entropy; how many of those bits can Facebook decode?
