Abstract
Methods and systems are disclosed for enhancing the security of a user device such as a voice command device. A computing device associated with the user device may be configured to receive an indication of a trigger, such as a predetermined word or passcode. In response to receiving the indication of the trigger, the computing device may be configured to determine a verification signal marker and to cause transmission of the verification signal marker. The computing device may receive an audio input comprising a voice command and a detected signal marker and verify the voice command based on a comparison of the detected signal marker and the verification signal marker. In response to the verifying the voice command, the computing device may be configured to cause execution of an operation associated with the voice command such as tuning to a specific channel on a nearby set-top box.
