Fonasjonstype

Fonasjonstype, also known as phonation type, refers to the manner in which the vocal folds (also called vocal cords) vibrate during phonation, which is the process of producing sound with the voice. There are three primary types of fonasjonstype: normal, modal, and falsetto.

Normal phonation is the most common and typically occurs in the middle range of the voice. It is characterized by a smooth, steady vibration of the vocal folds. This type of phonation is used in everyday speech and singing.

Modal phonation is similar to normal phonation but occurs at a lower pitch. It is often used in speaking and singing, particularly in lower registers. Modal phonation is characterized by a steady, even vibration of the vocal folds.

Falsetto phonation occurs at a higher pitch than normal or modal phonation. It is characterized by a thinner, more breathy sound and a less steady vibration of the vocal folds. Falsetto is often used in singing, particularly in higher registers, and can also be used in speaking, especially by children and some adults.

The choice of fonasjonstype can depend on various factors, including the pitch of the sound being produced, the desired quality of the voice, and the individual's vocal range. Voice disorders or injuries can also affect fonasjonstype, leading to changes in the vibration of the vocal folds.
