If you're looking for alternative ways to wake up your Google Home device, here are a few things you can say instead of Hey Google.
OK Google is the most common way to start a conversation with your Google Home. However, if you want to change it up or if you find Hey Google isn't working as well as it used to, try saying OK Boomer, Good morning, or even just Hello.
If you want to get more specific, address your device by name. You can change your Google Home's name in the Settings menu. Once you've changed it, try saying something like Ok [name], turn on the lights.
If you're still having trouble getting your device to respond, make sure the microphone is turned on and that there's nothing blocking it. Also, check the volume levels in the app and on your device itself.
