Recently, the significance of smooth communication between human and computer in various fields has been increased. As a means of communication between human and computer, human voice is paid attention to. On the realization of human-machine interface by human voice, which is the most familiar media, it is significant to discriminate the personality and emotion of the speaker and recognize the means of the word. However, in the past human speech analysis, the identification of the vibration characteristics of vocal chords is essential in order to establish new analysis method which is able to discriminate the personality and emotion of the speaker. In this study, the metal mass is fixed on the neck skin near the vocal chord and assume as a vibration system of one degree of freedom. Besides, the free vibration test is carried out in order to identify the system parameters, such as the mass m, the damping coefficient c and the stiffness coefficient k of the metal mass-neck skin system. The system parameters and the natural frequency are determined by the analysis of the free vibration tests. The forced vibration responses are obtained from the measurement by using laser displacement sensor in the forced oscillation test by utterance. From the experimental results, the vibration of vocal chords can be presumed.
