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.
1 Structural: A structural disorder refers to a problem with the voice mechanism itself. 2  In this case, there may be fluid in the vocal cords, polyps/cysts interfering with closure and vibration, etc. 3  Neurogenic: A neurogenic voice disorder refers to a disruption in the nerves controlling the larynx.
