Google Home Broadcast: Send Your Voice to Every Speaker in the House

Google Home's Broadcast feature is a built-in household intercom that sends your recorded voice message to every Google or Nest speaker in your home simultaneously. It is one of the simplest and most practical features of the Google Home ecosystem, and many families use it daily without realizing it has a name.

To use Broadcast, you say "Hey Google, broadcast [your message]" to any Google or Nest speaker in your home. Google records your voice message, then plays it through every other speaker in the house at the same time. If you say "Hey Google, broadcast dinner is ready," that phrase plays out loud on the Google Nest Mini in the bedroom, the Nest Hub in the kitchen, and any other Google Home device connected to the same Wi-Fi network.

The message plays in your actual voice, which family members recognize right away. This is more personal than a generic text-to-speech announcement and avoids the confusion of hearing an unfamiliar robotic voice.

Google has also added preset broadcasts for common household phrases. If you say "Hey Google, broadcast I'm home," Google plays a cheerful chime followed by a "Someone's home!" announcement. Phrases like "Wake up," "Dinner's ready," "Time to leave," and "I'm on my way home" all trigger specific audio clips rather than recording your voice. These work without thinking up what to say.

Broadcasts are one-way by default — the other speakers play the message but do not reply. If you want a two-way conversation between specific speakers, use the "Intercom" feature instead: say "Hey Google, intercom to the bedroom" to start a two-way audio connection with just the bedroom speaker.

For households with children who need reminders, elderly parents who may be in another room, or anyone who wants a simple way to communicate throughout the house without shouting, Google Home Broadcast is a practical tool that requires no setup beyond having Google or Nest speakers already working.
