Nvidia is today releasing version 6.0 of its software for the Shield TV set top box, which brings along the Google Assistant. First announced back at CES in January, Google Assistant on the Nvidia Shield TV allows for hands-free control of media playback, voice search, and smart home control. The Shield TV is the first Android TV device to get the full Google Assistant experience; Google says it will also come to Sony Bravia TVs with Android TV in the coming months.

Google Assistant on the Shield TV may sound very similar to the Google Voice Search that was available in prior versions, but it has been enhanced with a cleaner visual design and more capabilities. Nvidia says that apart from a handful of functions, such as timers, alarms, and phone calls, the Assistant on the Shield TV can do everything that it can do on the Google Home.
