In Vitro Experimental Investigation of Voice Production

Abstract:

The process of human phonation involves a complex interaction between the physical domains of structural dynamics, fluid flow, and acoustic sound production and radiation. Given the high degree of nonlinearity of these processes, even small anatomical or physiological disturbances can significantly affect the voice signal. In the worst cases, patients can lose their voice and hence the normal mode of speech communication. To improve medical therapies and surgical techniques it is very important to understand better the physics of the human phonation process. Due to the limited experimental access to the human larynx, alternative strategies, including artificial vocal folds, have been developed. The following review gives an overview of experimental investigations of artificial vocal folds within the last 30 years. The models are sorted into three groups: static models, externally driven models, and self-oscillating models. The focus is on the different models of the human vocal folds and on the ways in which they have been applied.

Keywords: Artificial vocal folds, flow-induced acoustics, fluid-structure-acoustic interaction, glottal fluid flow, human phonation, structural dynamics, voice, Physical Parameters, Membranous-Type Models, SELF-OSCILLATING MODELS
