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!
