Resonances and mode shapes of the human vocal tract during vowel production

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

We show that higher vowel formants may consist of multiple acoustic resonances. We compute the Helmholtz resonances of the vocal tract (VT) using FEM. The resulting resonance and pressure information is then compared to formants extracted from recorded vowel phonation. It is observed that the pure longitudinal modes appear in the sequence of all acoustic modes in an order that depends on the vowel even in a single test subject.
