    In this paper the numerical study of a simplified model of airflow through glottal region of the human vocal tract is addressed and the self-oscillating vocal fold is modelled. The main attention is paid to comparison of approximation of a coupled fluid-structure interaction problems to the results of a simplified aeroelastic model publishedearlier. The mathematical model is described by the airflow governed by the 2D incompressible Navier-Stokes equations. The structure vibrations are described with the aid of two-degrees of freedom model. The problem is numerically approximated by finite element method stabilized by Galerkin-Least Squares method, modified for the application on moving domains.
