Abstract

Summary: Objective. To review the current published available research into the impact of voice training on thevocal quality of professional voice users, to provide implications for vocal health and recommendations for furtherresearch.Design. Literature review with a systematic approach.Methods. A systematic search of the literature was conducted using electronic databases and the following definedsearch terms: occupational voice or occupational dysphonia or voice and occupational safety and health. To obtainthe comprehensive relevant literature, no studies were excluded on the basis of study design. In total, 10 studies thatinvestigated the impact of a voice training intervention on the vocal quality of professional voice users as a potentialprevention strategy for voice disorders were selected for this review.Results. The 10 studies ranged in design from observational to randomized controlled trials with mainly small samplesizes (N ¼ 11–60). Nine studies showed that voice training significantly (P < 0.05) improved at least one voice-relatedmeasurement from the several investigated from baseline. Five studies reported that voice training significantly(P < 0.05) improved at least one measurement compared with no training.Conclusions. Findings indicate that there is no conclusive evidence that voice training improves the vocal effectivenessof professional voice users, as a result of a range of methodological limitations of the included studies. However,some studies did show that voice training significantly improved the knowledge, awareness, and quality of voice. Therefore,there is a need for robust research to empirically confirm this, with implications for vocal health, and occupationalsafety and health policies.
