It wasn't always the case, but you can pair your Google smart speaker with any Bluetooth speaker.
Why would you want to do so? Well, this is an ideal solution for those who want the benefits of Google Assistant but want the sound to play through another speaker.
In the steps below, we'll show you how to do exactly that. Once everything is connected and paired, be sure to check out our full Google Assistant guide for more tips.
Google Home and Bluetooth pairing
To get started, turn on the Bluetooth speaker and stick it in pairing mode - probably via pressing and holding a dedicated button on the top or back of the device - and then follow these steps:
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.
Google Home Bluetooth pairing: How does it work?
Obviously, this feature is probably most beneficial 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, while it's not necessary, 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.
Can you pair more than one Bluetooth speaker?
Yes - 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.
Google Home Bluetooth: Correct the group delay
If you're having an issue with latency, you're able to easily troubleshoot the problem.
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.
