Answer 1

So the disconnect is when people say listening they actually mean two separate processes, there’s hearing the sounds and then theirs recording and storing what is said. The analogy is like sleeping, when ur fast asleep you are still listening, we know this cus if I call ur name loud enough you will probably wake up. But that doesn’t mean when ur fast alseep u can remember what is being said, cus ur listening without storing the information. Same thing with Siri it’s listening constantly but doesn’t wake up and record what you have said until you say hey siri.
