The purpose of this article was to systematically review the literature on the effects of biofeedback therapy in the domain of phonatory disorders and phonatory performance, using studies in peer-reviewed journals. An extensive definition of biofeedback is given and its place in voice treatment is defined. Eighteen group or case studies or reports considering the effects of electromyographic, laryngoscopic and acoustic biofeedback in dysphonic patients (hyperfunctional voice disorders, hypofunctional voice disorders, psychogenic voice disorder, laryngeal trauma, total laryngectomy, vocal cord dysfunction) and participants with normal voices are included and an analysis of procedure as well as research design and results is presented. The usefulness of biofeedback in phonatory disorders and performance was to be interpreted based on tendencies, since there is a lack of randomized controlled efficacy studies. In only 3 of 18 studies (16.7%) did biofeedback therapy fail to improve voice quality or not result in better results than other forms of therapy. Recommendations for improved methodologies are made, which include the use of acoustic voice quality parameters.

Notes
Holbrook et al. (1974) developed the Vocal Intensity Controller (VIC), a portable instrument that provided immediate auditory feedback contingent on vocal intensity and that automatically stimulated the speaker to avoid abusive loudness after a level-adjusted tone was presented through an earphone.
Vocal cord dysfunction is an obstructive upper airway syndrome that frequently simulates asthma and that is typified by paradoxical inspiratory vocal cord adduction producing wheezing, dyspnea, coughing and chest tightness and frequently induced by physical exercises. Treatment mostly relies on speech therapy with breathing exercises (Newman & Dubester, 1994).
