Voice recognition
Voice recognition overview
You can unlock the screen by using your voice.
• This function may not be supported depending on the service provider.
• This feature may be more vulnerable to security than the other screen
locks, such as Knock Code, Pattern, PIN, and Password.
• When a similar voice or your recorded voice is used, the screen may be
unlocked.
• When the voice recognition is selected for screen lock, you must enter
Knock Code, Pattern, PIN or Password that has been used for voice
registration instead of voice recognition after the power is turned on.
Make sure not to forget the specified value.
• If the device cannot detect your voice or you forget the screen lock set
for your device, visit the nearest LG Customer Service Center with your
device and ID card.
• The recognized voice data is securely stored in your device.
Precautions for voice recognition
Voice recognition accuracy may decrease in the following cases. To
increase its accuracy, check the following before using the device.
• When you speak different from the registered voice command.
• When you speak in a noisy place.
• When the microphone hole is covered with your hand or any foreign
substances.
• When the registered voice command is too short (3 to 5 syllables are
recommended).
