Effect of a soft tissue on vocal tract acoustic resonance properties in vocal exercises using phonation into tubes
Radolf, Vojtěch ; Horáček, Jaromír ; Laukkanen, A. M.
Mathematical model is introduced to clarify the influence of the vocal tract soft tissues on the acoustic resonance (formant) frequencies. The influence is studied in the context of voice therapy technique that uses phonation into tubes. Strong acoustc-structural interaction is demonstrated to take place in the vocal tract when it is prolonged by a tube with the distal end in air or submerged 2 cm and 10 cm in water. The numerical results from the model are compared with the resonance frequencies measured in humans.
