No they dont , they dont have to. Far easier to get things other ways.
Yes, but also no. You're underestimating advertisers' greed for data.
It's actually trivial nowadays to build a background service like that.
Which would show up in network traffic , which it doesnt. There is no need for it.
You could easily process the audio and filter in on the device and just send the transcribed parts that match your filters for further processing. No need to send a constant audio stream. Eventually it would show up in the battery usage but things like the google song recognition also heavily use the mic and process audio and it doesn't show up as heavy as you would expect.
is this still a surprise to anyone here?
Anyone whos said anything outloud and then immediately got an ad should know by now that it isnt some conspiracy, its easily testable by not searching something and just talking about it while having an app open, the more obvious one they track is dms, if I dm someone something (text based not posts) ill get ads or posts related to it.
Im assuming they target your wifi too, because my ads change to reflect what I do on other devices too (always noticable as a hobby hopper)

Yeah that sounds like an app user who would be okay with his audio being recorded...
An app where all you end up recording is "Bro! Bro! Bro! Broseeeeph! Let's gooooooo, Bro!"

How can they tell I'm popping?.... Oh....what if I stopped flushing? So is that why some people don't flush? They're trying to be stealthy!
