Influence of the Side Branches of the Human Vocal Tract on the Voice Quality

Popis výsledku v původním jazyce

The side branches of the human vocal tract exhibit antiresonance and resonance properties in the human voice frequency spectrum which influence the voice quality. This study investigates the possibility of these specific resonances to 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 on the acoustic resonance and antiresonance characteristics of the vocal tract. These models, created from an accurate three-dimensional (3D) FE models of the human vocal tract for vowel [a:,i:,u:], are computationally-effective and allows parametric changes of the parallel cavities continuously within the physiologic range. These changes are expected to play a role in voice therapy and operatic singing. While the influence of the geometric configuration of the main channel of the vocal tract on the vocal output has been studied rather extensively, the influence of side cavities of human vocal tract, has received less attention
