How to Set Up a Voice Screen Lock on Your Smartphone

Securing your smartphone with a unique and convenient method is becoming increasingly popular. One such method is using a voice screen lock, which allows you to unlock your device using voice commands. While not all smartphones come with built-in voice lock features, there are apps available that can help you set this up. Here’s a step-by-step guide to setting up a voice screen lock on your Android smartphone.

Step 1: Check Your Smartphone Compatibility

First, ensure that your smartphone supports voice recognition features. Most modern Android phones do, but it’s always good to check.

Step 2: Download a Voice Lock App

Since Android does not come with a built-in voice lock feature, you will need to download a third-party app from the Google Play Store. Some popular voice lock apps include:

  • Voice Lock Screen
  • AppLock by DoMobile Lab
  • Voice Screen Lock

Step 3: Install and Open the App

Download APP

  1. Go to the Google Play Store:
  • Search for “Voice Lock Screen” or any other voice lock app you prefer.
  • Select the app from the search results and tap “Install.”
  1. Open the App:
  • Once the app is installed, open it from your app drawer or directly from the Play Store.

Step 4: Set Up Your Voice Lock

  1. Grant Necessary Permissions:
  • When you first open the app, it will ask for various permissions, such as access to your microphone and storage. Grant these permissions for the app to function properly.
  1. Record Your Voice Command:
  • Follow the on-screen instructions to set up your voice command. Typically, you will need to record a phrase or word multiple times to ensure accuracy. Choose a phrase that is unique but easy for you to remember.
  1. Confirm and Save:
  • After recording your voice command, the app will ask you to confirm and save it. Make sure you test the voice command to ensure it works correctly.

Step 5: Enable Voice Lock

  1. Activate the Voice Lock:
  • Within the app settings, enable the voice lock feature. This might be labeled as “Enable Voice Lock” or “Activate Voice Unlock.”
  1. Set as Default Lock Screen:
  • Some apps will ask you to set the voice lock as your default lock screen. Follow the prompts to do this.
  1. Test the Lock:
  • Lock your phone and try unlocking it using the voice command you set up. Make sure it recognizes your voice accurately.

Step 6: Backup Lock Option

It’s always a good idea to have a backup unlocking method in case the voice lock fails to recognize your voice. Most apps will allow you to set a PIN, pattern, or password as a secondary unlock method.

Tips for Using Voice Lock

  • Clear Pronunciation: Make sure you record your voice command in a quiet environment and pronounce your words clearly.
  • Unique Phrase: Use a unique phrase that others are unlikely to guess.
  • Regular Testing: Periodically test your voice lock to ensure it’s still functioning correctly.


Setting up a voice screen lock on your smartphone can add an extra layer of security and convenience. By following these steps, you can easily secure your device with your unique voice command. Always remember to have a backup unlocking method to avoid getting locked out of your phone. Enjoy the ease and security of unlocking your phone with just your voice!
