I got my first Alexa the moment they added the computer wake word. Using computer as a wake word fucking sucks. When I finally get around to spinning up something open source, I'm gonna try using "Clockmaker" in reference to the SciFi series inspector Dreyfus by Alistair Reynolds
Once I took my car in to get serviced and I walked up to the desk to check it in and the lady said, "good morning!" Then I said, "good morning!" Then my phone said, "good morning!"
I actually have mine set like that right now! False positives are pretty low for me... except for when I watch Star Trek. Then my device chimes in whenever a character calls for it.
I've been rewatching Discovery, and it's made me learn that they talked to the computer a whole lot more in season 1... the interruptions seemed to drop off significantly after that.
Makes me think of how I always used to wonder what would happen if you had The Clapper connected to your TV when The Clapper commercial came on. Would you keep having to clap to turn your TV back on?
Really any loud noise could trigger it. I don't recall TVs really doing it, though. Maybe if the volume was way up, but in general I think they ignored normal levels of sound.
