The key elements in generating speech are the vocal folds and the vocal tract. This paper deals with the modelling of the creation of Czech vowels by means of vocal folds model and the models of the vocal tracts. The folds model was devised by using the finite elements method and vocal tract models were designed by means of magnetic resonance. Source sound created by means of the “air bubbles” method was modified by the transfer function of vocal tracts. Models were applied both in time and frequency domains. Spectral analysis of the signal was carried out and completed in the area of the mouth and it was crowned by the spectra of vowels /a/,/i/,/o/ with marked formants.

Index Terms. vowels, transfer function, spectrum, formants
