Abstract

The vocal folds are two multi-layered regions of tissue located in the larynx that vibrate as air flows past from the lungs. This vibration is the basis of voiced speech, one of mankind’s primary means of expression. Due to a complex fluid-structure-acoustic interaction and the inaccessibility of in vivo tissue for observation, synthetic models have been developed and used to study different aspects of the mechanics of speech production. This project compared the performance of two self-oscillating synthetic vocal fold models that differed in their composition of an internal tissue layer called the intermediate layer of the lamina propria. Until this project, difficulties in getting consistent models have been largely due to the thinness and embedded acrylic fiber in this layer.
