Numerical simulation of the speaker's formant for different geometric confuguration of the human vocal tract

Popis výsledku v původním jazyce

Various side branches of the human vocal tract exhibit antiresonances and resonances in the human voice frequency spectrum which influence the voice quality. This study investigates the possibility how these specific resonances can contribute to the speaker's formant cluster around 3-5 kHz. A reduced finite element (FE) models were created which allows numerical simulation of the effects of changing the parallel cavities volume on the acoustic resonance and antiresonance characteristics of the vocal tract. These simplified models, created from accurate three-dimensional (3D) FE models of the human vocal tract for vowel [a:,i:,u:], are computationally effective and allow parametric changes of the parallel cavities continuously within the human physiologic range. These changes are expected to play also a role in voice exercising, voice therapy and operatic singing.
