The study presents a three-dimensional (3D) finite element (FE) model of the flow-induced self-oscillation of the human vocal folds in interaction with acoustics in the simplified vocal tract models. The effect of vocal-fold layers thickness and material properties on simulated videokymographic (VKG) images and produced sound spectra is analyzed. The 3D vocal tract models of the acoustic spaces for Czech vowels [a:], [i:] and [u:] were created by converting the data from the magnetic resonance images (MRI). The fluid-structure interaction is solved using explicit coupling scheme with separated solvers for structure and fluid domain. For modelling the acoustic wave propagation, compressible Navier-Stokes equations were utilized. The developed FE model can be used to numerically simulate pathological changes in the vocal-fold tissue and their influence on the voice production.
