Do you recall the “ghost” incident, where Alexa believed she was being asked to laugh? What was Alexa hearing in your everyday life to believe that not only the trigger word, but the whole phrase was being said aloud?
Also, do you recall the fix? They remotely changed the activation phrase that triggered the laugh.
Do you recall the Google home devices with a minor physical flaw that caused the pucks to record and transmit everything?
Do you recall how these recordings are given to third parties to evaluate to improve the quality of the service?
I guess what I’m trying to say is that we don’t know when or if these devices are recording us. Yes, the same is true with our phones as well (though this bracelet from the article would work on them too). It might not be out of malice, but its safe to say that we as the customers have no real idea of how much they hear.
