Does Facebook record audio in app?

Does @facebook use audio from phone microphones for targeted advertising? If so, it’s brilliant and a bit unsettling. Friends are talking about it on twitter and I thought I’d ask the people who might actually know.

    Yes guys in a company where engineers can view any code we've started recording everything you say. No one has leaked this yet even though this would news of the decade.

    If this was true someone could easily setup a peer reviewed study to confirm this. It baffles me how many engineers lack basic logic and scientific reasoning.

    "How do they know so much" maybe because you spend a enormous amount of time telling an app what you like and don't like? Google and FB know more about most people then anyone else in their lives know about them.

    OP
    I figured it was just confirmation bias. Also it sounds like too much work/expense to be worth it. Just image the amount of audio data fb would have to process with all its users. Then there is the fundamental problem fb has always had. How do they figure out what text is economically relevant? If they have so much trouble really monitoring peoples interactions on fb as they do now, imagine the problem of trying to monetize people’s conversations. That’d be like reading minds.

      Audio data isnt much. Especially if the data is mono and 8k pcm, which is generally good enough for speech synthesis. Transcription isn't very hard. The resources is. You can build a model in the device to only upload audio with voice in it. Sample the audio do dsp and check. I mean I can tell you for a company with 500 billion in market capital, this issue is doable technically if they want to. What can they learn from it is questionable and of low value. People speak, but don't speak much commerical intent. That's where fb makes money.

      I think what prevents them is the privacy blowback.

    No, how would they be able to pull that off? 100% confirmation bias.

    lol what. No.

    Also For iPhone, to use the mic a colored bar will appear at the top. Kind of like when hotspot is on. Or you’re in a call.

    Just think of the technology required for that. Echo and Google Home can barely work with advanced microphones with trigger words.

    It would be a huge step forward in technology to passively record hours of conversation and pull out a few key words for targeted advertising.

    No way to do that on iPhone

    If you're on Android then die

    Most likely they do, and also your location and pictures/videos. Otherwise how do they know everything about you?

    this is the sort of thing you think is confirmation bias until one day, you have an "accident" you only speak about verbally, and fb advertises birth control to your gf for the next three weeks.

    Don't think this is still active in their current app version. Even still, it was opt-in only: http://www.smginsights.com/facebook-automatic-content-recognitionacr/
