- Voice production can be thought of as a source-filter model. The voice is a combination of a vibrating source that controls its amplitude and pitch (the five tones in the example above), and an acoustic filter that controls how it sounds, much like how you can shape the sound with a graphic equaliser on a sound system.

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.
The human voice is an extremely expressive instrument both when used for speech and for singing. By means of subtle variations of timing and pitch contour speakers and singers add a substantial amount of expressiveness to the linguistic or musical content and we are quite skilled in deciphering this information.
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.
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. Voice box brings both vocal folds apart during breathing. Role in cough reflex: close, then open glottis.
The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling. The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source. (Other sound production mechanisms ...
Jan 1, 2015 · Speech production is the process of uttering articulated sounds or words, i.e., how humans generate meaningful speech. It is a complex feedback process in which hearing, perception, and information processing in the nervous system and the brain are also involved.
