Dynamic mechanical modelling of speech
In voiced speech, the source of sound is the vibrations of the vocal folds within the larynx.

Abstract

In voiced speech, the source of sound is the vibrations of the vocal folds within the larynx. The steady flow of air passing out from the lungs is modulated by a complex fluid-tissue interaction in the larynx and excites acoustically the vocal tract downstream of the glottal exit. The system is small and inaccessible and, being situated inside a living person, is unsuitable for many kinds of experimentation. In vitro models offer the opportunity for systematic empirical studies in a controllable environment. This paper describes experimental measurements of the flow and pressure regimes made on a driven mechanical model of the vocal folds and vocal tract. The model has been used in a range of studies to explore jet formation and development downstream from the glottal exit, the effect of small changes in the duct geometry and, latterly, the interrelationship between the vibrating glottal source and a noise source further downstream as found in voiced fricative sounds.
