Hoarseness is having difficulty producing sound when trying to speak, or a change in the pitch or quality of the voice. The voice may sound weak, very breathy, scratchy, or husky.

Hoarseness is usually caused by a problem in the vocal cords. Most cases of hoarseness are associated with inflammation of the larynx (laryngitis).

Hoarseness that lingers for weeks or months may be caused by a variety of problems. Some causes are minor, while others are serious.

• Excessive use of alcohol or tobacco
• Excessive use of the voice (as in shouting or singing)
• Gastroesophageal reflux

Other causes include:

• Aneurysms of the upper aorta
