If you've ever owned a device like Alexa or Google Home what he said isn't confusing at all. They trigger accidentally all the time. His Alexa simply triggered when it wasn't supposed to and then reacted to what he was saying. Given he was gaming it was likely something about killing himself or someone else.

Huh, interesting. I have an amazon echo. My problem with it is not that it activates when I don't say trigger word, it's that I have to try very many times to get it triggered (usually by speaking louder).

It's impossible for me to say with certainty if it didn't just interpret something I said as it's trigger. Nevertheless, I was playing Halo online and yelling about a match going badly, saying something to the effect of "we might as well kill ourselves, this match is just not going our way" while laughing, and Alexa interpreted it as me contemplating suicide, and offered to connect me to a crisis line.

Great, now we need another device recording all sounds so we can play then back to reverse engineer smart speaker behavior :(
