Abstract
A head-mounted wearable device (HMWD) includes a plurality of microphones. These microphones may be used to acquire audio data produced by the user, such as speech, or sound from the ambient environment. In one implementation, a first air conduction (AC) microphone is emplaced at a bridge of the nose of the HMWD, a second AC microphone at a hinge, and a bone conduction (BC) microphone is positioned at a distal end of one of the temples of the HMWD. For example, the BC microphone may be located in the left temple proximate to the apex of the user's ear. A semi-rigid structure may provide mechanical coupling between the user's head and the BC microphone.
