How to turn on 'Ok Google' detection

All of those nifty Google voice commands are one of the major strengths of using an Android phone. But they’re even more powerful if you enable “Ok Google” detection from any screen. 

This means whether your phone is locked or you’re using another app, you can just speak a question or command to put Google’s search power to use.

To start, launch the Google app and open Settings > Ok Google detection. Then toggle From any screen.

Turn on the always-listening mode from the Google app.

Next you’ll be prompted to say, “Ok Google” three times so the app can learn how your voice sounds. This is to ensure only you can launch the Google search.

Teach Google how your voice sounds so no one else besides you initiates a search.

Once this is finished, you’re set to go. On the previous screen you can toggle Personal results to get suggestions based on what Google has learned about your search and browsing history. Additionally, you can enable “Ok Google” to work through a Bluetooth headset.
