Vocal tract changes caused by phonation into a tube: A case study using computer tomography and finite-element modeling
Original language description
Phonation into a glass tube is a voice training and therapy method that leads to beneficial effect in voice production. This pilot study examined the vocal tract shape in a female subject before, during, and after phonation into a tube using computer tomography (CT). 3D finite-element models (FEMs) of the vocal tract were derived from CT images and used to study pharyngeal closure and enlarged cross-sectional areas of the oropharyngeal and oral cavities during and after the tube-phonation. FEM calculations revealed an increased input inertance of the vocal tract and an increased acoustic energy radiated out of the vocal tract after the tube-phonation. The results indicate that the phonation into a tube causes changes in the vocal tract which remain also when the tube is removed.
