A question, out of my idle curiosity, how sensitive is Alexa to false triggers?
In over two years, I’ve had maybe half a dozen false triggers on my Apple Watch, where it picks up some background noise that it thinks is somebody saying “hey Siri” co-incident with me raising my arm. It then listens to what follows, trying to find a meaningful command, meaning the subsequent soundtrack is all uploaded. It does tap me on the wrist to let me know it is listening.
Most often, “Hey Siri” has been falsely detected when there is background conversations (babble) going on, it has happened on public transport, and when watching TV. But on one occasion last week I was alone in the house, emptying the dishwasher. No radio or TV, no voices, somehow it constructed a “Hey Siri” from the clatter of saucepans.
