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.
When people have a voice disorder, their voice may: Have a quivering sound. Sound rough or harsh (hoarse). Sound strained or choppy. Be weak, whispery, or breathy. Be too high or low or change in pitch. They may have tension or pain in their throat while speaking, or feel like their voice box is tired.
