3 Mechanisms of Voice Production
The aim of this chapter is to provide an overview of laryngeal anatomy and physiology, characteristics of vocal fold motion, transformation of vocal fold vibration to sound, and mechanisms of vocal fold vibration. Throughout the chapter computational models have been used for demonstration purposes to generate examples of vocal fold motion and resulting waveforms representing various quantities.
متن کاملAcoustics of Human Voice Production
Human voice production is studied as an acoustic process inside the vocal tract using the wave equation for air, and compared with large-scale databases of simultaneously acquired microphone and electroglottograph signals. The following theories are confirmed: For voiced sounds, the process starts at glottal closures. Immediately before a glottal closure, there is a continuous airflow in the vo...
متن کاملOccupational Voice - Studying Voice Production and Preventing Voice Problems with Special Emphasis on Call-centre Employees
This thesis deals with the occupational voice. In modern society, there is an increasing demand for oral communication in many professions. The label ‘occupational voice’ refers to those occupations where voice is the major tool. Employees in these occupations often suffer from voice symptoms to varying extents. In this thesis, the telephone customer service advisors are the target group of pro...
متن کاملMechanics of human voice production and control.
As the primary means of communication, voice plays an important role in daily life. Voice also conveys personal information such as social status, personal traits, and the emotional state of the speaker. Mechanically, voice production involves complex fluid-structure interaction within the glottis and its control by laryngeal muscle activation. An important goal of voice research is to establis...
