| Abstract;Voice recognition utilizing bone-conductedvoice,which robust under noisy environment,has been investigated. The suitavility for voice recognition and voice communication of bone-conducted voice recorded at several measurement popints on human head was evaluated using LPC cepstrum distance and Speech Transmission Index. Experimental results show that forehead and cheek are good as the aquisition points of bone-conducted voice. In order to improve the quality of bone-conducted voice, a novel sensor, which has an inclined frequccy responce, was fabricated. Using this sensor, acquired bone-conducted voice has a similar frequency response as that of air-conducted voice. |
