Geometric Model of Tongue During Phonation of Vowel /a/

Original language description

The aim of this study was to investigate an effect of acuteness and intensity of phonation for tongue shape and position. That is crucial for creation of a parametric geometric model of human vocal tract for simulation and analysis of phonation. The geometric model of a tongue during phonation of the vowel /a/ was created. The model was based on magnetic resonance images. 26 year old volunteer was scanned in sagittal plane by T1 weighted sequence. Number of slices (17) and their thickness (4mm) were chosen with respect to ability of volunteer to keep phonation constant in time for one breath. The measurements were carried out for 3 different acuteness of phonation and for 3 different intensity of phonation /a/. Phonation acuteness increase causes flattening of posterior tongue part and its translation in posterior direction. Phonation intensity increase causes flattening of posterior part and rise of anterior part of tongue.
