Chen Presents Short Course for World Voice Day
Dr. Julian Chengjun Chen recently gave a short course on The Transient Theory of Human Voice Production, to celebrate World Voice Day (April 16, 2023) at the Voice Study Centre in Bergholt, England, UK. World Voice Day is an annual celebration established by the Voice Committee of the American Academy of Otolaryngology - Head and Neck Surgery.
The transient theory of human voice production and applications were detailed in Prof. Chen's monograph Elements of Human Voice (2017). According to ResearchGate, now it has 6035 reads and 14 citations. His monograph was intended to replace the 50+ year old orthodoxy, the source-filter theory of human voice production, with a transient theory of human voice production, initially formulated by Leonhard Euler in 1727.
Dr. Chen's invitation to present a graduate-level course on the occasion of World Voice Day highlights his contributions to the academic community. Because the audience was likely not familiar with physics and mathematics, his entire presentation was made with graphics, rather than equations. Only high-school level mathematics and physics--the concept of energy conservation--were mentioned. A video of the presentation, linked below, is available for anyone interested, including those outside of APAM: for example, students majoring in vocal music, physiology, or medicine.
