Abstract
The disclosed devices and methods provide beamforming for a head-worn microphone array that can adapt to changes in the user's head position/orientation. The microphone array may be part of a head-worn computing device, which can be configured to automatically detect a direction for the beamforming based on computer-assisted recognition of a conversation with a participant. After the participant is identified, the beamforming can automatically steer the sensitivity of the microphone array towards the participant regardless of the position of the head user to improve a quality of the captured audio without constraining movement of a user. The improved audio may be used to aid in a user's hearing of the conversation, aid an augmented reality application corresponding to the conversation, and/or provide a degree of privacy by limiting sensitivity to participants in the conversation.
