Voice therapies have proven to be an effective method of helping patients avoid the symptoms of vocal fatigue. This study assesses the effect of a chant-based therapy on self-perceptive symptoms of vocal fatigue. A recitational pattern was selected and a therapy regime created from important features of this chant. It was administered along with a placebo therapy to four public school teachers who were prone to vocal fatigue. A two-hour fatiguing task was administered pre- and post-therapies, during which self-evaluative measures of "vocal effort" and "voice quality" were made by the subjects. The plots of these measures were used for the purpose of determining the effects of the chant therapy. Based on changes in the subjects' responses to the fatiguing task after the delivery of the chant therapy, we concluded that this form of functional therapy has the potential to be effective in the remediation of vocal fatigue.

Comprehensive Literature Search

Purpose The purpose of this document is threefold: (a) review the uses of the terms “vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading” (as found in the literature) in order to track the occurrence and the related evolution of research; (b) present a “linguistically modeled” definition of the same from the review of literature on the terms; and (c) propose conceptualized definitions of the concepts. Method A comprehensive literature search was conducted using PubMed/MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scientific Electronic Library Online. Four terms (“vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading”), as well as possible variants, were included in the search, and their usages were compiled into conceptual definitions. Finally, a focus group of eight experts in the field (current authors) worked together to make conceptual connections and proposed consensus definitions. Results The occurrence and frequency of “vocal load,” “vocal loading,” “vocal effort,” and “vocal fatigue” in the literature are presented, and summary definitions are developed. The results indicate that these terms appear to be often interchanged with blurred distinctions. Therefore, the focus group proposes the use of two new terms, “vocal demand” and “vocal demand response,” in place of the terms “vocal load” and “vocal loading.” We also propose standardized definitions for all four concepts. Conclusion Through a comprehensive literature search, the terms “vocal fatigue,” “vocal effort,” “vocal load,” and “vocal loading” were explored, new terms were proposed, and standardized definitions were presented. Future work should refine these proposed definitions as research continues to address vocal health concerns.
