ACTIVATING FUNCTIONS IN PROCESSING DEVICES USING ENCODED AUDIO AND DETECTING AUDIO SIGNATURES

Methods and apparatus for performing an action on a device based on audio are disclosed. An example method includes determining at a first device whether the audio includes a monitoring code indicating that the audio is to be monitored, generating a signature using a portion of the audio containing the monitoring code, and causing the action to be performed on a second device based on at least one of the monitoring code or the signature.
