listening and just reacts to the trigger word "Alexa" or whatever you set it to but I don't buy it. It has to always be listening in order to hear Alexa so there's that. As far as the other stuff, Samsung had to acknowledge that their TVs were always listening and sending your conversations out over the internet back to their hub.

I've also heard of people having a conversation in a vehicle that had an Android phone IN it but not recording nor on a call. The conversation was very specific and random and the phone owner had Google ads targeted on the same topic the next day. It was something really random like cranberry farming hydraulic hoses and the phone owner hadn't ever heard of it before the in car conversation.
