Users of Nvidia’s SHIELD Android TV set-top box will soon be able to add this $50 microphone/speaker combo, which plugs into any available wall socket and works in a similar way to Amazon Echo and Google Home. Powered like the latter by Google Assistant, you can use it to control smart home/IoT devices, navigate YouTube, Netflix, Amazon Video, Google Play and Vudu using voice commands, search the web, order takeaway food and more.
