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.
