In this work a three-dimensional (3D) finite element (FE) model of the flow-induced self-sustained oscillation of the human vocal folds is presented and combined with the acoustics of vocal tract models. The developed complex FE model consists of the FE model of the vocal folds and the FE models of the trachea and of the simplified acoustic spaces of the human vocal tract shaped for phonation of Czech vowels [a:], [i:] and [u:]. The developed FE model can be used to numerically simulate voice production, including pathological changes in the vocal fold tissue and their influence on the voice production.
