To date, there are 300 disorders associated with voice, but until now there has never been a published reference manual that classifies these disorders. Borrowing from the successful organization schema of the American Psychiatric Association’s Diagnostic Statistical Manual (DSM), the Classification Manual for Voice Disorders-I provides the framework for classifying voice disorders using the following criteria for each disorder: essential and associated features; vocal impairment; clinical history and demographic profile; course and complications; medical and voice differential diagnosis; and severity criteria.
Classification Manual for Voice Disorders-I is a project of ASHA’s Special Interest Division 3, Voice and Voice Disorders (DIV 3), originally directed by contributing authors Moya Andrews, Diane Bless, Daniel Boone, Janina Casper, Leslie Glaze, Mike Karnell, Christy Ludlow, and Joe Stemple. The text was edited over a period of several years by the authoritative group of voice disorders professionals, including Katherine Verdolini, Clark Rosen, and Ryan Branski. This version represents the fields of speech-language pathology, voice science, and otolaryngology.
