Vocal folds
Vocal Folds
Vocal folds (pronounced: VOH-kul fohlds), also known as vocal cords, are a pair of flexible bands of muscle tissue that are located in the larynx (pronounced: LAIR-inks), or voice box.
Etymology
The term "vocal folds" comes from the Latin vocalis (relating to voice) and the Old English fealdan (to fold).
Function
The primary function of the vocal folds is to produce sound for speech. They do this by vibrating at different speeds to create different pitches. The speed of vibration is controlled by the brain and the nervous system.

Problems with the vocal folds can lead to a variety of voice disorders. These can include hoarseness, voice fatigue, and dysphonia (difficulty speaking). Treatment for these conditions can involve voice therapy, medication, or in some cases, surgery.
