WORLD VOICE DAY – April 16, 2024

History of WORLD VOICE DAY

The human voice has existed for as long as humans ourselves have been in existence. A comprehensive history of the origins and use of the human voice for millennia of human history may prove arduous, if not outright possible. However, the biological construct theories of the human voice are a good explanation of how the voice works, and for this discussion, we think that would be more than enough.

The human voice consists of sounds produced by a human being through the vocal tract. Some of the action resulting from this includes talking, singing, laughing, crying, screaming, shouting, and humming, among other things. The voice frequency of human beings plays a specifically important role in the production of suns, in which specific vocal folds or cords make up the primary source of the sound. Other mechanisms of human sound production from the same body region usually involve the production of “unvoiced consonants,” clicks, whistling, and whispering.

The mechanism for generating or producing a sound frequency from the human voice is divided into the lungs, the voice box (vocal folds within the larynx), and the articulators. For the sound production equation to work, the lungs must produce enough airflow and pressure to create vibrations in the vocal folds through its pump action. The vocal folds then work with this air pressure from the lungs to develop audible pulses that make up the larynx’s sound source. The laryngeal muscles adjust the length and the tension of the vocal folds to determine specific pitch and tone. The articulators are the parts of the vocal tract above the larynx, which comprise the tongue, palate, cheek, and lips. They filter the sound produced from the larynx and, to certain extents, can strengthen or weaken laryngeal airflow as a sound source by interacting with it.
