If Alexa, Cortana and Siri aren't always listening, how can they pick their names out of conversations?

Want an honest answer?

Onboard are >=2 bits of code. At least one of those is a specific system trained to recognize a "wake word". This specific system (ostensibly) doesn't send anything to an outside party. Its entire job is to recognize one wake phrase: Alexa, Ok Google, or Siri, and then if that wake phrase is used it responds and tells the second system to listen. As you can imagine, this is a pretty easy job to get right 80% of the time. So that can be put on a chip. So then it does its job, and it's the second system that sends everything to an internet service for whatever reason.

I didn't ask for honesty!

I'd love to have this properly audited sometime. I'd slap like to think that we're generally protected from big companies doing unethical and unjust things to us, by law, ... but nah

(That's not to say I don't believe this explanation; the second half of my comment was just an addendum.)
