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 establish a causal theory linking voice physiology and biomechanics to how speakers use and control voice to communicate meaning and personal information.
The Process of Voice. Voice production involves a three-step process. A column of air pressure is moved towards the vocal folds. Air is moved out of the lungs and towards the vocal folds by coordinated action of the diaphragm, abdominal muscles, chest muscles, and rib cage.
Vocal tract: throat (pharynx), oral cavity, nasal passages. Changes the “buzzy sound” into a person’s recognizable voice. Key Function of the Voice Box. The key function of the voice box is to open and close the glottis (the space between the two vocal folds). Role in breathing: Open glottis.
Jul 10, 2018 · “Voice” is the complex interaction of the vocal mechanism with the rest of the body used to produce speech and song (melody, rhythm, and language) as well as so-called vegetative sounds, such as coughing, crying, screaming, and so on.
This article provides details on human speech production involving a range of physical features, which may have evolved as specific adaptations for this purpose. All mammalian vocalizations are produced similarly, involving features that primarily evolved for respiration or ingestion.
The source-filter theory, schematically illustrated in Fig. 16.19, describes vocal sound production as a three-step process: (1) generation of a steady flow of air from the lungs (DC component); (2) conversion of this airflow into a pseudo-periodically pulsating transglottal airflow (DC-to-AC conversion), referred to as the voice source; and (3 ...

The ability to produce voice starts with airflow from the lungs, which is coordinated by the action of the diaphragm and abdominal and chest muscles. Vibratory System. The voice box (larynx) and vocal folds (sometimes called vocal cords) comprise the vibratory system of the voice mechanism. Resonating System.
