We've been getting lots of false positives, as well, but it seems to have started happening suddenly. I wonder if it's related to a recent software update.
We often get false positives as well. I've wished there were some way to signal a false positive to the device after Siri is activated, like "Siri, I didn't ask for you," to help it learn/train it. Not sure how feasible such a function would be, but I imagine it would be helpful feedback down the line on the engineering end. Anything to reduce the false positives would be great as they are a) a nuisance and b) further confirmation to friends/family who witness it, that we've made a mistake allowing a "surveillance" device in our home.
Have you noticed that certain queries that used to work have stopped giving you the expected response?
I've started noticing more false positives since iOS 12 launched, and there's a couple requests that now don't give me the expected response. The most annoying issue happens to be requesting Siri to set an alarm. I'll ask: "Hey Siri, turn on my 6:15am alarm." to which she'll respond, "Which alarm do you want to turn on..." and then list all the different alarms I've set on the HomePod.
This all changed with iOS 12, and I wonder if I should reach out to Apple or just live with it and hope it improves with a software update??
Late response, but here's the thing...that alarm does exist and is listed off when Siri goes through all the existing alarm options that can be turned on...
