Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing , particularly during inhalation .
Glottal insufficiency (when the vocal folds cannot close completely, often due to vocal fold paralysis) can also be an underlying cause of contact granulomas. [ 5 ] Contact trauma can occur when a person frequently speaks at a pitch that is lower than their modal voice , especially in vocally-demanding professions like acting, teaching and ...
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.
The adducted vocal folds do not close completely but instead remain partially open. The narrow opening between the folds is referred to as the glottis . [ 23 ] [ 7 ] As air moves through the glottis, it causes a distortion of the air particles which sets the vocal folds into vibratory motion.
It was not simple for her." As a result, Nyong'o's vocal cords paid the price. At one point in her recording sessions, which took years to complete, Sanders was notified that Nyong'o needed to go ...
Videostroboscopy is a high-speed medical imaging method used to visualize the dynamics of human vocal fold vibration. When stimulated by the pressure of breath exhaled from the lungs, the two vocal folds (also known as vocal cords) open and close rapidly. This process is called phonation and produces the sound of the human voice.

Vocal fold lesions such as a vocal fold nodule or other changes in the vocal fold mucosa can lead to increased tension in the larynx and cause dysphonia. [2] Larynogopharyngeal reflux, a process that is similar to GERD, can bring stomach acid into the larynx. This can provoke the larynx to tense to prevent the aspiration of the acid. [3]
