Abstract
An audio device may be configured to work in conjunction with a handheld remote controller to receive voice commands from a user. The audio device may have multiple local microphones that are used for sound source localization, to determine the position of the user. A remote audio signal may be received from the remote controller and used in conjunction with local microphone signals generated by the local microphones to aid in determining the position of the user. The last known position of the user may be recorded whenever the user speaks into the remote controller. When the user is unable to find the remote controller, the audio device may direct the user toward the last known position of the user.
