Influence of velopharyngeal insufficiency on phonation of Czech vowels


Abstract eng:
The effects of velopharyngeal insufficiency on acoustic frequency– modal characteristics of human supraglottal spaces are investigated. The finite element model was developed from magnetic resonance images (MRI) of the subject during phonation. The influence of the velopharyngeal insufficiency on phonation of the Czech vowels /A,I,U/ is numerically simulated in time domain. The Liljecrants-Fant’s pulse is used for excitation of the acoustic system.
