Another day, another Alexa skill, right? Well the latest set is pretty useful if you feel like talking to your TV actually responding when you yell at it. With Sony's 2017 4K models with HDR and Android TV you can turn them on and off, adjust volume, input and even start and stop playback with your voice. You can change the channel too, if your cable box is attached to your TV with an HDMI cable. The folks at Logitech Harmony has gotten in on the voice-control action too, in addition to BroadLink and its collection of Hubs.
