A reduced-order three-dimensional continuum model of voice production

Although vocal fold vibration largely occurs in the transverse plane, control of voice is mainly achieved by adjusting vocal fold stiffness along the anterior–posterior direction through muscle activation. Thus, models of voice control need to be at least three-dimensional on the structural side. Modeling the detailed three-dimensional interaction between vocal fold dynamics, glottal aerodynamics, and the sub- and supra-glottal acoustics is computationally expensive, which prevents parametric studies of voice production using three-dimensional models. In this study, a Galerkin-based reduced-order three-dimensional continuum model of phonation was presented. Preliminary results showed that this model was able to qualitatively reproduce previous experimental observations. This model is computationally efficient and thus ideal for parametric studies in phonation research as well as practical applications such as speech synthesis. [Work supported by NIH.]
