Home treatment that includes resting the vocal cords, using a humidifier and drinking plenty of liquids is typically all that is needed to cure laryngitis, according to WebMD. Whispering, which irritates the vocal cords, should be avoided, while talking quietly as necessary is best.
Avoiding smoking as well as second-hand smoke is also essential to getting over a case of laryngitis, according to WebMD. Most cases of laryngitis are healed within two weeks. In cases of chronic laryngitis, speech training may be needed to correct a problem with speaking that is causing the laryngitis, or surgery may be needed to remove sores or polyps causing the problem.
