In linguistics, creaky voice (sometimes called laryngealisation, pulse phonation, vocal fry, or glottal fry), is a special kind of phonation in which the arytenoid cartilages in the larynx are drawn together; as a result, the vocal folds are compressed rather tightly, becoming relatively slack and compact. They vibrate irregularly at 20–50 pulses per second, about two octaves below the frequency of normal voicing, and the airflow through the glottis is very slow. However, although creaky voice may occur with very low pitch, as at the end of a long intonation unit, it can occur with any pitch.
A slight degree of laryngealisation, occurring in some Korean consonants for example, is called "stiff voice". The Danish prosodic feature stød is an example of a form of laryngealisation that has a phonemic function. Creaky voice is also prevalent in English as spoken in the Pacific Northwest of the United States.
