By this adaption, vibrations of both voiced and 64 1 unvoiced human speech are sensed, and high speech intelligibility is obtained in an acoustically-noisy environment. The transducer appa- ratus may be realized in numerous embodiments. In one embodiment, the vibration-sensing transducer is embodied in a earset or headset connected to an electronic device with a microphone input. The out- put of the vibration-sensing transducer is connected to the microphone input of the electronic device. 60
