The Lee Silverman Voice Treatment was developed for patients with Parkinson's disease and has been applied to various types of disorders in which the vocal folds fail to close. The focus is on increasing breath support to maintain loudness at a preset level.

Other voice therapy techniques also exist. The technique used depends on the patient's disorder, his or her ability to identify changes in the voice with the technique used and the interpersonal relationship between the patient and the voice specialist. Voice therapy should always be done by a licensed and certified speech-language pathologist. In some instances, patients, especially singers, are also referred to singing teachers for special help with repertoire and techniques to aid in the recovery of the voice problem.
