When it comes to home automation voice assistants, Amazon has led the pack for a while, with the Echo, Dot, and Tap devices. These clever gadgets are always listening for your commands (or in the case of Tap, press a button and then it will listen) and act accordingly. I've used my Echo to listen to music ("Alexa, play Smooth Jazz") and to control some of my smart home devices. It's as close to a Star Trek computer as possible, at least until we can wear a communicator badge! There are even third-party apps that sit on top of the Echo system, in the cloud, so you can play trivia, etc., all controlled by voice.
