In Part I, I discussed physiology of the larynx during phonation; voice testing, classification, and diagnosis.1 This second paper describes the specific therapeutic approach used for the restoration of normal laryngeal muscle balance, as currently used in the Department of Otolaryngology at the State University of New York, Upstate Medical Center at Syracuse.

To be fully effective, voice therapy must restore the normal dynamic equilibrium of the intrinsic and cricothyroid muscles which control the functions of the vocal cords. Further, the patient must learn how to maintain this equilibrium. This requires specific, thorough, and precise adjustment of these muscles. Voice therapy naturally divides itself into four distinct but closely interrelated phases:

  1. The first, or Dehabiting Phase, during which voice habits indicative of abuse are identified and corrected

  2. The Muscle Retraining Phase during which correction.

  3. Widening of safety margin, by training all muscles to endure
