Název v původním jazyce

Influence of piriform sinuses and valleculae on the resonance and antiresonance characteristics of the human vocal tract - numerical simulation

Popis výsledku v původním jazyce

The influence of the vocal tract on vocal output has been studied rather extensively, the influence of side cavities of human vocal tract, such as the piriform sinuses (PS) and valleculae (VA) has received much less attention. Generally, these cavities have been reported to cause antiresonances in the resulting vocal spectrum. However, a more detailed analysis reveals that besides the antiformants there are also new formants which occur due to these side cavities. The contribution investigates the influence of PS and VA and their size on the resonance and antiresonance characteristics of the vocal tract using a reduced FE model of the human vocal tract.
