      There are exceptional profiling abilities Facebook uses based on physical proximity for friends suggestions, but not aware for advertising.

      Humans exceptionally good at finding patterns or social anomalies, such as when advertising occasionally seems to be keyed off a life event.

      Also doesn't help that social networks (1) want to appear all-knowing to advertisers. (2) appear innocuous to users. Leads to lack of info.

      With the rise of perpetually active microphones, good mobile connectivity, high-quality voice recognition, and vast computing power... (1/2)

      these fears are no longer *physically* impossible on an individual level. But in practice, in the current context, it's not realistic. (2/2)

      Note that there is an app technology that can recognize audio codes embedded in radio and TV. But that's a whole other thing than speech. 🙃

      also note: iOS doesn't provide an API for apps to access call audio, and using the mic in background displays a double-height red status bar

      Ah yes, I was interpreting question as in-person audio while using the app

      yeah, foreground apps can use the mic invisibly, which is how those ultrasonic tracking things work (iOS should really indicate this)

      if random apps getting paid for tracking showed a mic icon in the status bar all the time, I get the feeling they'd cut that shit out

      Even moreso if they had to explicitly request access the first time.

          They do have to do that already, but if there's anything stopping them from using it for other stuff afterwards, it's just policy (not tech)
