Techniques for processing voice commands from a locked device are described. A voice command received by a locked device is stored, a prompt requesting that the device be unlocked is generated, and the voice command is processed automatically after the device is unlocked. Thus, the system processes the voice command without the user repeating the voice command. In addition, the system may process certain voice commands even when the device is locked. For example, a whitelist filter compares an intent associated with the voice command to whitelisted intents from a whitelist database before the intent is dispatched to a speechlet, and intents included in the whitelist database are processed normally. Thus, the system performs certain voice commands while the device is locked, while other voice commands may be automatically processed after the device is unlocked without the user repeating the voice command.
