vocal cords









































the vocal cords, also known as vocal folds, are folds of tissue in the throat that are key in creating sounds through vocalization. the size of vocal cords affects the pitch of voice. open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal branch of the vagus nerve.









































they are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. they vibrate, modulating the flow of air being expelled from the lungs during phonation.

vocal cords
if the vocal cords are completely relaxed, with the arytenoid cartilages apart for maximum airflow, the cords do not vibrate. this is voiceless phonation, and is extremely common with obstruents. if the arytenoids are pressed together for glottal closure, the vocal cords block the airstream, producing stop sounds such as the glottal stop. in between there is a sweet spot of maximum vibration. also, the existence of an optimal glottal shape for ease of phonation has been shown, at which the lung pressure required to initiate the vocal cord vibration is minimum. this is modal voice, and is the normal state for vowels and sonorants in all the world's languages. however, the aperture of the arytenoid cartilages, and therefore the tension in the vocal cords, is one of degree between the end points of open and closed, and there are several intermediate situations utilized by various languages to make contrasting sounds.
