Voice Unlock The Phone Using Google Assistant

Note - You already know that Google voice feature is not available in certain Android phones such as Android 8.0 and upwards. Unfortunately Google have extracted the feature from this version. Android 5.0 to Android 7.1.2 are compatible.

Unlocking your Android phone with Google assistant is a very convenient feature. You simply have to say 'Ok Google' to wake the assistant. Make sure you have the right Android device to make use of this.

To enable this feature let's take a look at some settings.

You need the Google assistant to recognize your voice so you will have to register your own voice for this purpose. Google assistant needs a trusted voice model.

Now head to Assistant settings and allow voice unlock.

Both of the above settings can be accessed by launching Google assistant. Let's take a look at these steps. You will see a 'Drawer' icon in blue color which is in the Google assistant interface. Tap this 'Drawer' icon.


Now tap the 'Menu' button which is the three dots and select 'Settings'. Tap your phone under the 'Devices'.


Afterward to allow both 'Access with voice match' and then 'Unlock with voice match'. That's it!


Now you will be asked to train a voice model to unlock your device. Make sure you train a trusted voice so your Google assistant will only recognize your own voice.

When you are done with the above procedures the app will ask you to record a few words or sentences. This will allow the assistant to recognize your voice swiftly. For some reason if you are not happy with your previous voice training you can always retrain them. For the retraining option, go to the same setting menu as above and under the menu you will see 'Voice model' then tap 'Retrain voice model'. Simple as that.

Google assistant will accept only one voice model at a time to ensure the security is tight. This is only necessary when your Google assistant couldn't detect your voice because of noisy surroundings or your microphone volume is quite low. We all know that in Google home we can set more than one voice but it's not the same in your mobile phones.

Voice unlock issues you may face

If your lock screen is protected from other security procedures unlocking with your voice using Google assistant wouldn't be a smooth task sometimes. Your screen wouldn't take you past the security screen in case if your phone is password protected by using a fingerprint scanner, face detection ID, uses patterns to unlock or PIN. This will only wake up your screen but not go past it. You can remove all your security measures but that is not advisable. let's see why..

It is better to delay the time your phone locks automatically, by doing this your phone will be inactive for quite some time which will demand a security method. Now your phone won't lock soon after your screen goes to the sleep mode so you can enable voice lock.

To make use of this feature head to 'Settings > Security and location' and then you will find a 'Gear' icon beside 'Screen lock'. Tap the 'Gear' icon.


Next tap 'Automatically lock' to delay the process.


You can also set up 'Google smart lock' in the same menu. By setting this up you can connect your device with another trusted device or Bluetooth connection and your phone wouldn't lock immediately so that you can wake your device with your voice without needing a password.

Voice unlocking is not reliable always as it will mistake someone else's voice which looks similar and trusted. Android devices vary in specifications and some phones will unlock for trusted voices.

Some Android devices have this vexing issue where the voice unlock will work only if the phone is on.
