This study investigates incompressible airflow through the human vocal folds. The fluid motion is for- mulated within the arbitrary Lagrangian–Eulerian (ALE) framework to account for the moving computational domain. The governing equations are discretized using the finite element method (FEM) with Taylor–Hood elements. To ensure numerical stability in convection-dominated regimes, streamline upwind Petrov–Galerkin (SUPG) and grad–div stabilization techniques are employed. The proposed numerical framework is applied to simulations with prescribed vocal fold motion based on a kinematic model. Numerical results are validated against available experimental data for the static M5 vocal folds geometry, showing good agreement. In addi- tion, a simulation of the soft voice regime is presented.
