Shield TV, Nvidia’s streaming media set-top box introduced last year, is going hands-free by way of Alexa. The company announced this morning the launch of a new Amazon Alexa skill which will enable Shield TV owners in the U.S. to navigate their device with voice commands, including those to turn on or off the Shield, adjust the volume, play, pause, fast-forward, or rewind content, or even move around to various sections, like the Home screen or Settings.

With the addition, Shield TV owners can now choose between Alexa or Google Home Assistant devices, in terms of hands-free voice control.
