Have someone hide your phone (or just misplace it like I always do). Walk around the house and say this, loudly… “OK, Google… Make a bunch of noise so I can find you.”
My phone’s response was, “This is a Tractor.” Followed by a long sample of a tractor engine. Needless to say I found my phone. It was under a couch cushion. 🤪 I’m sure I’ll need this feature again. 😉
