    Model for self-oscillations of vocal folds and finite element (FE) models of acoustic spaces of the human vocal tract were developed and combined in order to numerically simulate the production of Czech vowels /a/,/e/,/i/,/o/ and /u/. The vocal tract was excited at the position of the vocal folds by a derivative of the airflow rate passing through the oscillating glottis. The resulting acoustic pressure at the location of the lips is numerically simulated in time domain.

    Kombinací modelu pro samobuzené kmity hlasivek a konečně prvkového modelu akustických prostor lidského vokálního traktu je numericky simulována fonace českých samohlásek /a,e,i,o,u/. Vokální trakt byl buzen v místě hlasivek derivací objemového průtoku vzduchu proudícího kmitajícími hlasivkami. Výsledné akustické tlaky u úst jsou numericky simulovány v časové oblasti.
