| Abstract: | Biomechanical modeling is carried out to study register transitions of the human voice. Registers and their transitions play an important role not only in the singing voice but also in the expressive speech. Our model has a body-cover structure, which is composed of fourth masses. A smooth geometry is realized by introducing a polygon shape to the vocal fold model. The simulation study shows that the model can reproduce many complex phenomena such as register jumps, hysteresis, subharmonics, and chaos, observed in excised larynx experiment as well as in vocalization of untrained singers. Influence of the subglottal and supraglottal resonances on the transition point of the registers is also investigated in detail. |
