Original Abstract

Finite element (FE) model of the acoustic space corresponding to the human vocal tract for Czech vowel /a/ and acoustic space around the human head was used for numerical simulations. The resonant characteristics of the FE model are studied using modal and transient analyses. The production of vowel /a/ is simulated in time domain using transient analysis of FE model excited by Liljencrants-Fants (LF) glottal signal model. The results of numerical simulations are in good agreement with experimental data known from literature. Solution in the time domain allows to create sound files for an acoustic verification of the quality of numerically produced vowel by listening. Designed FE model allows also observing radiation of acoustic waves from the lips to the outer acoustic space.
