Voice Disorders. A voice disorder is when the voice has a problem with pitch, volume, tone, and other qualities. These problems occur when the vocal cords don't vibrate normally. Your voice is the sound that air makes when it is forced out of your lungs and passes over your vocal cords.
Vocal cord disorders can affect your voice or ability to talk. Some of the more common vocal cord disorders include laryngitis, vocal nodules, vocal polyps, and vocal cord paralysis. Vocal cord disorders are often caused by vocal abuse or misuse.
