Before you begin troubleshooting, try the following steps to resolve your issue:
- Install the latest version of Voice Access. Voice Access should automatically update based on your Android Play Store settings, but you can always manually check for updates on Google Play.
- Install the latest version of the Google app. With older versions of the Google app, saying "Ok Google" doesn't automatically start Voice Access, so make sure you're using the latest version.
- Use the recommended configuration. Refer to "Step 1: Check your device and settings" in Get started with Voice Access.
If Voice Access still isn't working, try the steps below.
Voice Access doesn't recognize voice commandsIf Voice Access doesn't recognize your voice commands, try the following:
- Make sure that your device is connected to the Internet over cellular data or Wi-Fi.
- Move to a quiet place.
- Speak more slowly and clearly.
- Try using a headset with a microphone.
- Repeat your voice command.
- Turn off vibration in your device settings. Vibration might interfere with speech recognition.
If Voice Access appears to freeze, wait a few seconds. You might need to do this if you say a long command or if another app tries to listen to you at the same time.
The only lock screen currently supported by Voice Access is the PIN unlock. To protect your security when you enter your PIN, Voice Access shows random words on the screen (such as "red" or "blue") instead of Voice Access number labels. This way you can say the words instead of your PIN numbers. You can change your lock screen in Settings 
If you have trouble starting Voice Access on the lock screen, try the following steps:
- In the Google app, go to Settings
Voice, then turn on Unlock with Voice Match or Trusted voice. This setting lets you use "Ok Google" to turn on Voice Access from the lock screen. Learn more about "Ok Google". (Note: The availability of this setting varies by device.)
- In Voice Access settings, turn on "Activate on lock screen." This setting automatically starts Voice Access when the screen turns on, if the lock screen is showing. Learn how to change your Voice Access settings.
- Connect your device to a Bluetooth switch or keyboard, then use the switch or keyboard to start Voice Access on the lock screen. For more information about setting up a Bluetooth switch, see instructions to start Voice Access.
- Set up your device for automatic unlock. You can pair a trusted Bluetooth device or NFC tag to your device to unlock it automatically for you. Learn more about Smart Lock.
To turn on the screen by voice, go to the Google app

Voice Access uses almost no battery when it's inactive, but it uses more battery when listening for your commands. Consider using Voice Access while your device is connected to a power supply if you find that your battery is draining faster than normal.
