Experiments with Analysis By Synthesis of Glottal Airflow

The glottal model is based on a mechanical system with two basic degrees of freedom and is a variation on the classical two-mass model of Ishizaka and Flanagan (1972). A distinctive characteristic is that the two resonators are here organized as a translational system and a superimposed rotational system. Both resonator systems use one and the same mass element. The resonators are separately driven by the aerodynamics, the translational by the space average pressure in the glottal passage, and the rotational by the pressure gradient in the flow direction. The resonators are thus indirectly coupled by the aerodynamics. Experiences in static and dynamic approximations to natural voices using an analysis by synthesis strategy are summarized.
