Resumo

Some discrepancies have occurred between physiological data for the larynx and the dynamic models which have been proposed in the literature. For instance, recents tomograms of the larynx during phonation has shown the entry angle of the glottis to be more abrupt than that chosen for these models. Also the false vocal folds seem to avoid the assumption of the uniform vocal tract adopted for some models reported. Results presented here show the influence of these figures on the glottal waveforms.

Abstract

Some discrepancies have occurred between physiological data for the larynx and the dynamic models which have been proposed in the literature. For instance, recents tomograms of the larynx during phonation has shown the entry angle of the glottis to be more abrupt than that chosen for these models. Also the false vocal folds seem to avoid the assumption of the uniform vocal tract adopted for some models reported. Results presented here show the influence of these figures on the glottal waveforms.
