Phonation
Phonation
Phonation (/foʊˈneɪʃən/) is the process by which the vocal folds produce certain sounds through controlled, periodic vibration. This process is fundamental to vocal communication and is a critical component of speech and singing.
Etymology
The term "phonation" has its roots in the Greek word "phone," which means voice or sound. It was first used in the context of vocal production in the late 19th century.
Process
Phonation involves the complex interaction of the larynx, vocal folds, and respiratory system. When air from the lungs passes through the vocal folds, they vibrate, producing sound. The pitch and volume of the sound can be modified by altering the tension and shape of the vocal folds.
Types of Phonation
There are several types of phonation, including:
- Modal voice: This is the most common type of phonation, used in normal speech and singing.
- Falsetto: This is a lighter register that requires the vocal folds to stretch and thin.
- Vocal fry: This is a low, creaky voice quality produced by loose vocal fold closure.
Related Terms

- Larynx: Also known as the voice box, this is the part of the throat that houses the vocal folds.
- Respiratory system: The system in the body responsible for breathing, which supplies the air needed for phonation.
