This discovery surprised people, but it shouldn’t have. The things around us are increasingly computerized, and increasingly connected to the Internet. And most of them are listening.
Our smartphones and computers, of course, listen to us when we’re making audio and video calls. But the microphones are always there, and there are ways a hacker, government, or clever company can turn those microphones on without our knowledge. Sometimes we turn them on ourselves. If we have an iPhone, the voice-processing system Siri listens to us, but only when we push the iPhone’s button. Like Samsung, iPhones with the “Hey Siri” feature enabled listen all the time. So do Android devices with the “OK Google” feature enabled, and so does an Amazon voice-activated system called Echo. Facebook has the ability to turn your smartphone’s microphone on when you’re using the app.
