Hoarseness




Abnormal changes in the voice are called “hoarseness.” When hoarse, the voice may sound breathy, raspy, strained, or show changes in volume or pitch (depending on how high or low the voice is). Voice changes are related to disorders in the sound-producing parts (vocal folds) of the voice box (larynx). While breathing, the vocal folds remain apart. When speaking or singing, they come together and, as air leaves the lungs, they vibrate, producing sound. Swelling or lumps on the vocal folds hinder vibration, altering voice quality, volume, and pitch.
