Vocal Fatigue

Abstract
The phenomenon of vocal fatigue, although not well understood, is commonly considered a symptom of voice misuse. This paper reviews the clinical and experimental evidence linking vocal fatigue to the quality, pitch, and loudness of voice use. Other reasons for voice change are discussed. The paper concludes by stressing the immediate clinical benefits of voice endurance testing as well as its potential experimental contribution to a better scientific understanding of optimum and abusive vocal behavior.
