How to Broadcast Messages on Google Assistant Speakers and Displays


If you have a number of Google Home or Nest speakers and Smart Displays scattered around your house, why not put them to use as a broadcasting system? That’s exactly what you can do with the Google Assistant.

Google Assistant’s broadcasting feature works like a modern intercom. You can broadcast a message to your kid’s room to tell them dinner is ready, or send a message to the whole house when you’re away. It’s a very useful feature.

Before we get into the process of broadcasting messages, let’s cover some basics. You can broadcast a message from the Google Assistant on your smartphone or tablet, or a Google Nest or Home device that’s a part of your smart home.

Broadcasts can be sent to every Google Nest or Home device in your house, or directed to specific rooms and devices. It’s also possible to reply to a broadcasted message.

Launch the Google Assistant

To use a Google Home or Nest smart speaker or Smart Display, you simply need to say “Hey, Google” and one of the commands below. With an iPhone, iPad, or Android device, you need to launch Google Assistant.

On Android, there are a number of different ways to launch the Google Assistant. The first is to say “OK, Google” or “Hey, Google.” Newer devices can launch the Assistant with a swipe from the bottom left or right corner.

On iPhone and iPad, you need to install the Google Assistant app and launch it from the home screen. After you open the app, say “OK, Google” or tap the “Microphone” icon and Assistant will begin listening.

Broadcast a Message

To broadcast a message to every Google Nest or Home device in your house, use one of the following commands:

  • “Broadcast [message].”
  • “Announce [message].”

To specify where the message will be broadcast, use these commands:

  • “Broadcast to [room name] [message].”
  • “Broadcast to [device name] [message].”

The difference between these two phrases is the first one will broadcast on every device in the room, whereas the latter will broadcast on only the mentioned device. You can find the name of each device and room using the Google Home app on iPhone, iPad, or Android.

Respond to a Broadcast

Responding to a broadcast works in a similar way as sending one. After the Google Assistant is done reciting the message from a speaker or Smart Display, say “Hey, Google” and the following commands:

  • “Reply [message].”
  • “Send a reply” (Google will follow-up and ask what the message is).

Your reply will only be sent to the original broadcasting device. If the original message was sent from a phone, they will get a notification with your response. If the original message came from a Google Home or Nest speaker or Smart Display, your response will be played out loud on the device.
