A head-mounted wearable device incorporates a transducer into a nosepiece. Vibrations from the user's speech are transferred through the bridge of the nose and are detected by the transducer to produce an audio signal. In one implementation, a nose plate with a pair of attached nosepieces is mounted to a transducer, such as an accelerometer. The nose plate may be affixed to a front frame of the head-mounted wearable device using a motion limiter mechanism.
