Finite element (FE) models of real male vocal and nasal tract corresponding to the Czech vowels / i / and / u / are analyzed in this paper. The FE models were designed by direct transferring data obtained from MRI images. The acoustic signals for the Czech vowels / i / and / u / are simulated using transient analysis of investigated FE models in time domain. The frequency and time response functions are calculated in the FE nodes near the lips, nostrils and at the vocal folds. Both FE models involve the effect of cleft palate. Results of numerical solution are compared with the acoustic modal analysis.
