- Voice is generated by airflow from the lungs. When the air from the lungs blows through the vocal folds at a high speed, the vocal folds vibrate. The vibrations lead to sounds we call voice. These sounds are shaped to form speech.

How has vocology changed our understanding of voice & vocal production?
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.
Mar 13, 2023 · Speech is produced by several parts of the body working together to shape the sounds of the voice. 1. Lungs. Voice is generated by airflow from the lungs. When the air from the lungs blows through the vocal folds at a high speed, the vocal folds vibrate. The vibrations lead to sounds we call voice.
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.
Human vocal tract articulation is much faster, and humans are able to produce multiple sounds on a single breath movement, inhalation or exhalation. The unique form of the tongue within the vocal tract in humans is considered to be a key factor in the speech-related flexibility of supralaryngeal vocal tract.
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.
Jul 10, 2018 · The voice is the primary source of human communication, whether verbal or nonverbal, melodic, or percussive. It is the complex interaction of the vocal mechanism (respiratory system, vocal folds, and the vocal tract) with the rest of the body that is used to produce speech, song (melody, rhythm, and language) as well as so-called vegetative ...
