Description
  • Acoustic properties of a physical model of real male vocal tract corresponding to the Czech vowel / a / are analyzed by the experimental modal analysis. The model was obtained from the magnetic resonance images (MRI), taken during the subject phonation by the method of rapid prototyping. The random excitation was applied at the vocal folds and the response was measured along the vocal tract. The frequency response functions were evaluated by a global identification method. The resulting eigenfrequencies (formants) and the acoustic mode shapes of vibration are compared with the acoustic measurements carried out during the MRI realization.

  • Práce se zabývá experimentalní frekvenčně-modální akustickou analýzou modelu mužského vokálního traktu. Model byl vytvořen metodou rapid prototyping z dat získaných při vyšetření fonujícího subjektu metodou magnetické rezonance (MRI). Náhodné buzení bylo aplikováno v rovině hlasivek a odezva byla snímána podél vokálního traktu. Globální identifikační metodou byly stanoveny vlastní frekvence a akustické tvary kmitu. Vlastní frekvence jsou porovnány s výsledky s akustickým měřením během záznamu MRI. (cs)
