I am a big fan of voice control in my home. I was recently telling a friend that I voice control my home using my smart TV. My friend uses Google Assistant on his phone and wanted to know if he could use it on his TV, so I gathered some information for him.

How do I set up and use Google Assistant on my TV? Some Smart TVs have a built-in Google Assistant. Set up and link the TV to your Google account in the Google Assistant app on a phone or tablet. TV and phone/tablet must be on the same Wi-Fi network.

There is so much to know about setting up and using Google Assistant enabled TVs, but if your TV does not have a built-in Google Assistant, don’t worry. You can still voice control your TV with a Chromecast device and a Google Home device. In the guide below, I have shared all the information I found about the different options for Google Assistant and TV integration.

Google Assistant on a TV

Many smart TVs come with a built-in Google Assistant such as Android TVs and LG ThinQ Smart TVs. Check out this list of smart TVs with built-in Google Assistant.

Setting up Google Assistant on Your Smart TV

Use these simple steps to set up your TV’s built-in Google Assistant:

  1. Set up your smart TV using the instructions from the TV manufacturer.
  2. If you do not already have the Google Assistant app, download it onto your phone or tablet. Sign into the app with your Google account.
  3. Ensure that your TV is connected to the same Wi-Fi network as your phone or tablet. Your home may have two Wi-Fi networks- 2.4 GHz and 5 GHz.
  4. In the Google Assistant app, say or type “Set up my assistant device”.
  5. The app will take you through the setup process. Follow the directions.

Using Google Assistant on Your TV

Your smart TV comes with a remote that is equipped with a microphone button and/or a Google Assistant button. Press and hold the button to speak to your Google Assistant. No wake word is required when using the button.

Some remotes will also respond to “Hey Google” or “Ok Google” without pressing the button. Test it out to see if your smart TV remote has this feature.

You can also teach Google Assistant to recognize your voice as a way to protect your personal information. Click here for directions to set up and use the Voice Match feature.

Voice Commands

As expected, Google Assistant on your TV can control your TV. Here are some of the commands you can use to control your TV:

  • “Play [name of show or movie] on [name of streaming service]”.
  • “Pause”
  • “Resume”
  • “Rewind [amount of time]”
  • “Fast forward [amount of time]”
  • “Open [name of streaming service]”.
  • “Search for [genre or type or show].”
  • “Volume [up/down]”.

In addition to controlling your TV, your TV’s Google Assistant also responds to other commands that you would use on your phone or Google Home device such as “What’s the weather today?” and “Turn off the lamp”. Here’s a list of the different Google Assistant commands.

Google Assistant Settings

If you share your Google Assistant enabled TV with roommates, you may want to limit its capabilities on the shared TV to protect your personal information.

  1. In the Google Assistant app on your phone or tablet, select the menu icon.
  2. Choose “Assistant”.
  3. Select your shared TV.
  4. Slide the “Personal results” bar off.

Turning the “Personal results” setting off will prevent others from accessing your calendar, lists, reminders, and photos via Google Assistant on your shared TV. You can turn this setting on and off as you wish.

Chromecast and Google Assistant

If your TV does not have a built-in Google Assistant, you can still voice control your TV with a Chromecast device and a Google Home device. All Google Home and Nest speakers and displays are compatible with Chromecast.

Setting up Chromecast on Your TV

Here are the steps to set up a Chromecast device:

  1. Plug the Chromecast power cable into an outlet. A Chromecast Ultra can also be powered with an Ethernet cable connected to your home’s internet.
  2. Plug the Chromecast device into an HDMI input on your TV.
  3. Turn on the TV and select the HDMI input that your Chromecast device is plugged into.  
  4. Open the Google Home app on your phone or tablet.
  5. Follow the steps in the app.
  6. Select your Wi-Fi network and enter your Wi-Fi password. Your phone or tablet, Chromecast device, and Google Home device must all be on the same Wi-Fi network.
  7. Select the streaming services you use. Some may require you to link your accounts. Click here for a list of voice-supported video streaming apps and directions to link them. 
  8. Name your Chromecast device to complete the setup process.

Linking Google Home and Chromecast

Once both devices are set up on the same Wi-Fi network, you will need to link them in the Google Home app using these steps:

  1. In the Google Home app, select your Chromecast device.
  2. Select the settings icon.
  3. Select “More settings”.
  4. Select “TV and speakers”.
  5. Tap on the + sign.
  6. Select your Chromecast device and tap “Add”.
