i use siri to turn off and on hue lights (sometimes) and sometimes to set reminders. I do feel that since I dont have Siri on an "always on" speaker, it becomes less useful. I dislike the idea of having an "always on" speaker, so I'm not sure what to do. :)

If it makes you feel better, the “always on” recordings never leave your device. They’re not even that great at recognizing anything other than “this sounds like a ‘hey Siri’”.

For a fun experiment, yell RED FIRE TRUCK into your phone then immediately activate Siri manually.

With Hey Siri turned on, you will reliably get all three words. With it off, you will usually get Chuck or Truck, or sometimes FIRETRUCK depending on timing.

This seems to be for people who start talking before the Siri prompt is fully active like “Set <button> Timer for 5 minutes”.

But shows that Apple is typically pre-recording if not also pre-processing.

I don’t get anything, just activates Siri normally.

I’m on iphone8 and can get it to happen reliably. Weird.

How old is your iPhone? I don’t recall the first model to introduce it, but all iPhones now I believe have supported an “always on” hey Siri mode for a while, even if phone is in standby.

Yup, the first iPhone to introduce this was iPhone 6s.

Oh, well maybe it is on then...
