Finite element model of male vocal tract considering clefting and interaction between hard palate and acoustic spaces
Dedouch K., Horáček J., Vampola T.
pages 60 - +6p., full text

Results of a voice numerical simulation using finite element (FE) model of acoustic spaces corresponding to the human vocal tract for English vowel / a / are presented. The approximate FE model was designed according to the data published in literature and amended by the model the nasal tract joint with the vocal tract by compliant bone of hard palate. The pronunciation of the vowel / a / is simulated using transient time analysis of the model. The acoustic pulse is realized by the time dependent displacement of a small circular plate moving in the plane of vocal folds. The time and frequency response functions are calculated in the points situated near the lips, the nostrils and at the vocal folds.
