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.
