My wife's phone regularly (maybe once a month), starts listening in response to me saying something, which isn't even "Hey Siri", despite never training with my voice. My voice does not sound anything like my wife's.

So, I think the error rate is simply not low enough to make conclusive claims about what it might or might not do.

It happens to me many times a day. I've b come acutely aware of how much I question other people because it activates when I say "Are you serious?"

Better stock up on those tinfoils.
