The voice: glottal flows, vocal tract resonances and their interaction

点击翻译按钮获取中文摘要

Speech is fundamental to human culture and huge industries exist that analyse, compress, synthesise, transmit and distribute it. Nevertheless, several practical difficulties mean that some key variables and how they interact are only imprecisely known. This project uses an innovative approach for deriving the glottal flow and a new technique for generating precise acoustical flows in model systems to refine the algorithms currently used to relate speech sound to the acoustic flow in the larynx. The project aims to provide the first reliable measurements of the bandwidths of resonances and the acoustical losses in vocal tracts. The results will have practical industrial and, perhaps, clinical applications.
