Smartphone security is more important than ever, and Android users are always looking for faster and smarter ways to lock their phones. One such method is a voice screen lock, which allows you to unlock your phone using your voice.
In this guide, you’ll learn how to set up a voice screen lock on your Android phone easily, what apps to use, and important safety tips.
What Is a Voice Screen Lock?
A voice screen lock lets you unlock your Android phone by speaking a custom voice command or phrase, such as:
- “Open my phone”
- “Hello Android”
- “Unlock now”
Your phone recognizes your voice and unlocks the screen automatically.
⚠️ Note: Most Android phones do not have a built-in voice lock, so you’ll need a trusted third-party app.
Is Voice Screen Lock Safe?
Voice screen lock is:
- ✅ Convenient
- ✅ Hands-free
- ❌ Not as secure as fingerprint or PIN
It’s best used as:
- A secondary lock
- For personal or low-risk use
- Accessibility or convenience purposes
Method 1: Set Up Voice Screen Lock Using a Third-Party App
Step 1: Download a Voice Screen Lock App
Go to Google Play Store and search for:
- “Voice Screen Lock”
- “Voice Lock – Unlock by Voice”
Popular options include:
- Voice Screen Lock
- Voice Lock Screen
- Smart Voice Lock
(Choose apps with high ratings and recent updates.)
Step 2: Open the App and Set a Voice Password
- Open the app
- Tap Enable Voice Lock
- Record your voice command
- Repeat the phrase for confirmation
- Save your voice password
Example:
“My phone is secure”
Step 3: Set a Backup Lock (Important)
Always set a backup PIN or pattern in case:
- Voice is not recognized
- You’re in a noisy environment
- App crashes
This ensures you never get locked out.
Step 4: Activate the Lock Screen
- Enable the app as your default lock screen
- Grant required permissions
- Lock your phone and test your voice command
Your phone should unlock when it recognizes your voice.
Method 2: Use Google Assistant (Limited Functionality)
Google Assistant can unlock certain features using Voice Match, but:
❌ It does NOT fully unlock the phone screen
✅ It can unlock apps or perform actions after initial unlock
Steps:
- Open Google Assistant
- Go to Settings → Voice Match
- Train your voice model
- Enable “Hey Google”
This method is not a full screen lock, but useful for voice access.

✅ Enable backup PIN or fingerprint
✅ Do not rely on voice lock for banking apps
✅ Keep the app updated

Setting up a voice screen lock on your Android phone is simple and fun, but it should be used carefully. While it adds convenience, it should never fully replace PIN, fingerprint, or face lock.
Use voice lock as an extra layer, not your only protection.
