It wasn't always this way, but you can pair your Google Home smart speaker with any Bluetooth speaker.
That's great if you want in on Google Assistant but you're happy with the sound quality of your existing speakers. Follow these easy steps to get going, and be sure to check out our full Google Assistant guide after for more
Pair with a Bluetooth speaker
To get started, turn on the Bluetooth speaker then stick it in pairing mode - probably via pressing and holding a dedicated button on the top or back of the device. Then you need to do the following:
1. Open the Google Home app.
2. Tap the Google Home you want to pair on the main overview screen.
3. Tap the cog icon at the top right.
4. Scroll down and select Paired Bluetooth devices.
5. Tap Enable Pairing Mode at the bottom right of the screen.
You should see the Bluetooth speaker appear on this screen, so just select it to pair. You can also set the Bluetooth speaker as your default Google Assistant speaker. Go back to the speaker's settings (the cog icon) but this time tap on Default speaker, which you'll see under Device settings.
Once they're paired and the speaker you want is set as default, just use any regular Google Assistant command and the audio and music will be played on the Bluetooth speaker instead.
Chat to Google Home, listen via Bluetooth
The new feature works across the Google Home family, all the way from the cute Mini to the powerful Max. Obviously, this feature is probably most going to benefit Mini owners, as Google's tiny smart speaker doesn't deliver a great performance in sound quality.
Be aware that all your Google Home's audio will route through your Bluetooth speakers if you do this. So if you ask for the weather, your Bluetooth speakers will play the answer - not your Google Home.
You will still have to actually speak to the Google Home too, as your Bluetooth speakers can't hear your commands and route them through the Home. So it's not necessary, but it makes sense to place them relatively near to each other in the room as you'll no doubt look towards the speaker you're trying to control.
Group more than one speaker
Yes, we said speakers - as in more than one. All you have to do is add a second Google Home/Chromecast built in or Chromecast Audio-connected speaker in a group and you'll automatically enable multi-room audio, voice controlled by the Google Home smart speaker.
So, just like a Sonos system, you can walk from room to room and they'll all play the same thing so that you don't miss a melody or word of your podcast.
The tricky thing here is that it's the Google Home smart speaker that you add to the multi-room group, not a Bluetooth speaker. It is possible to connect Wi-Fi and Bluetooth speakers around the house, though.
To create a group, simply open the Google Home app and tap Add, which you'll see in the control dock at the top of the Home screen. Then select Create speaker group. You'll be able to select the speakers you want before giving the group a name.
Then you can voice control all speakers with one command. So long as the Bluetooth speaker is paired to the Google Home, it will be added to the group.
Correct the group delay (if there is one)
You might need to adjust for the playback delay on the Bluetooth or Chromecast Audio speaker/s if you hear a substantial delay regularly.
To do this, you need to correct the speaker individually. So select the offending speaker from the home screen, tap the cog icon, then select Group delay correction.
You need to then play music on the problem speaker and a speaker with no delay, at similar volume then move the slider left and right to correct the delay. (Google recommends to always increase the correction for the speaker that plays last not the other way round.) That will then be applied to all the speakers in the group.
