Description
  • The aim of this study was to investigate an effect of acuteness and intensity of phonation for shape and position of human tongue. 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 images obtained from magnetic resonance imaging. Number of slices and their thickness were chosen with respect to ability of volunteer to keep phonation constant in time for one breath. The comfortable time of phonation was experimentally established to 15s.The measurements were carried out for 3 different acuteness and for 3 different intensity of phonation /a/. Tongue boundary was described by closed Coons spline . 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.

  • Cílem této práce bylo zjistit vliv hloubky a intenzity fonace na tvar a polohu jazyka pro budoucí tvorbu parametrického geometrického modelu vokálního traktu pro simulaci fonace člověka. Byl vytvořen geometrický popis jazyka při fonaci samohlásky /a/. Popis byl vytvořen na základě snímků z magnetické rezonance. Subjekt byl snímán v sagitální rovině T1 váženou sekvencí. řezy tloušťky 4mm. Počet řezů a jejich tloušťka, byly voleny s ohledem na pokusnou osobu tak, aby byla schopna přibližně konstantní fonace po celou dobu snímání. Pokusy stanovená pohodlná doba konstantní fonace 15 s nebyla při snímání překročena. Bylo provedeno měření pro 3 různé hloubky a 3 různé intenzity fonace hlásky /a/. K popisu tvaru hranice jazyka byla zvolena uzavřená Coonsova kubika. Při rostoucí výšce fonace dochází ke zplošťování posteriorní části jazyka a jeho posun v posteriorním směru. Při rostoucí intenzitě fonace dochází ke zplošťování posteriorní části jazyka a zvyšování jeho anteriorní části. (cs)
