Phonation

Falsetto ( , ; Italian diminutive of , "false") is the vocal register occupying the frequency range just above the modal voice register and overlapping with it by approximately one octave. It is produced by the vibration of the ligamentous edges of the vocal cords, in whole or in part. Commonly cited in the context of singing, falsetto, a characteristic of phonation by both sexes, is also one of four main spoken vocal registers recognized by speech pathology.

The term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation or phonating is the process by which the vocal cords, or vocal folds, produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process voicing, and use the term phonation to refer to any oscillatory state of any part of the larynx that modifies the airstream, of which voicing is just

In linguistics, voicelessness is the property of sounds being pronounced without the larynx vibrating. Phonologically, it is a type of phonation, which contrasts with other states of the larynx, but some object that the word phonation implies voicing and that voicelessness is the lack of phonation.

vocal practices found in different cultures of the world and that may involve a wide range of techniques for producing voice and song

phonation in which the arytenoid cartilages in the larynx are drawn together so that the vocal folds are tightly compressed and vibrate irregularly at 20–50 pulses per second, about 2 octaves below normal voice

phonation in which the vocal folds vibrate, as they do in normal (modal) voicing, but are adjusted to let more air escape which produces a sighing-like sound

Puberphonia (also known as mutational falsetto, functional falsetto, incomplete mutation, adolescent falsetto, or pubescent falsetto) is a functional voice disorder that is characterized by the habitual use of a high-pitched voice after puberty, hence why many refer to the disorder as resulting in a 'falsetto' voice. The voice may also be heard as breathy, rough, and lacking in power. The onset of puberphonia usually occurs in adolescence, between the ages of 11 and 15 years, at the same time as changes related to puberty are occurring. This disorder usually occurs in the absence of other comm
