It's not you, it's them: Google, Alexa and Siri may answer even if you haven't called

One in every four adults in America now owns a voice-activated smart speaker. While we love the convenience of talking to a gadget to play music, make calls, and such, most of us get a little creeped out when they "wake up" when they're not supposed to. I often trigger Siri when saying "seriously," or "Suli" – the name of my parents' dog. My friend Bill Keeshan says his Alexa connected device "gets triggered by my daughter saying'actually.'" All too familiar anecdotes aside, researchers at Northeastern University and the Imperial College of London spent the last six months streaming 125 hours of popular Netflix TV shows to a handful of voice-activated smart speakers.
