Scientific knowledge on the physiology of human voice production is the basis for improving voice health as well as diagnosing and treating voice and hearing disorders. According to Max Planck, &quot;Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination.&quot; In 1957, French physiologist Philippe Fabre invented the electroglottograph, which can detect the closing and opening of the glottis in vivo. In 1984, Donald Miller and Harm Schutte further placed two pressure sensors immediately above and below the glottis. The simultaneously acquired voice, electroglottograph, as well as the subglottal and supraglottal pressure signals in vivo composed a comprehensive experimental evidence of human voice production. By analyzing the experimental findings using the wave equation of sound, the following facts are established. First, the source of the acoustic energy of human voice is the kinetic energy of moving air in the vocal tract at the instant of a glottal closing. Second, each decaying acoustic wave triggered by a glottal closing contains full information on the timbre of the voice, therefore called a timbron. A sustained voice is the linear superposition of timbrons triggered by a series of glottal closings. Third, pitch period could be defined as the time interval between two consecutive glottal closings. Based on the timbron theory, a pitch-synchronous voice analysis method and programs are developed, which can be applied to improve voice diagnosis and rehabilitation, as well as all of speech technology, including voice transformation, speech coding, speech recognition, and speech synthesis. 

World ENT Congress 2022

Physiology of human voice production revealed by in-vivo experiments

This  conference will explore the intersection of technology and service, the lessons learned through the past extraordinary year, and the value of change management. In light of the challenging times, we are coming together virtually to share our work under the theme 'Leading with Innovation, Stronger through Collaboration'.

The UC Libraries Forum will serve as an opportunity for UC library colleagues to meet virtually, share, learn and find opportunities for new collaborations and projects across the UC system. Presentations and conversation will note existing collaborations and spark ideas for new ones. This forum builds on and extends the scope of UC DLFx 2018 and 2019 beyond digital initiatives to all library employees to include themes such as research data, scholarly communications, the current-COVID academic library and others.

keynote

World ENT Congress 2022 is an international conference that encourages effective knowledge transfer and best practices experts from around all the world. ENT 2022 is organized by the International Community and hosted by the SunText Reviews.

The World ENT Congress aims to strengthen the participants’ action and impact on national, regional, and international scales through a multidisciplinary program that features the integration of new technologies in the field of scientific improvements in ENT and Otorhinolaryngology.

World ENT Congress 2022 is scheduled in the Disney World and Universal Orlando. Orlando, being one of the centers for research, education, and science in the USA, we will try to bring the maximum number of Academicians, Researchers and Innovators, Experts, Industrialists, Professors, Researchers, Students, and Technical Staff, Engineers and Delegates, Product Developers, Solution Providers, Sales & Marketing Professionals, Associations, Societies, & Professional Bodies, Directors/Co-Directors of Research-based companies, and workshop teams to provide a better understanding of the field.
