​​Paper Presentation - Randomized Control Trial: Vocal Combat Technique for Video Game Voice Over Actors

Importance: Professional voice users are known to be at risk for phonotrauma, which impedes occupational functionality. Current vocal techniques to prevent, minimize, and recover from phonotrauma have not specifically been developed to retain functionality and realism for voice over actors who voice soundtracks for video games. Objective: To evaluate the efficacy of a direct voice therapy program for video game voice over actors—namely, Vocal Combat Technique—in: 1. reducing vocal fatigue and 2. preserving realism. Design: Prospective, double-blinded, randomized controlled study. Method: Twenty-four voice over actors (10 males, 14 females) were randomly assigned to 1 of 2 interventions: a) Vocal Combat Technique (VCT) or b) Vocal Hygiene Education (VHE). Pre- and Post- scores to measure vocal fatigue were collected for the Vocal Handicap Index (VHI), Evaluation of Ability to Sing Easily (EASE), and Vocal Tract Discomfort Scale – Frequency/Severity (VTDSF/VTDSS, respectively). A blinded industry professional judged all participants on realism and acceptability per industry standards. Result: Both groups were judged to be acceptable in preserving realism. Statistically significant differences were seen between groups in regards to change in EASE and VHI scores. No statistically significant differences were seen between groups in regards to change in VTDSF or VTDSS scores. Trends were seen within group outliers. Conclusions: The data suggest that VCT may help prevent, minimize, and recover from the impacts of phonotrauma while preserving occupational functionality for video game voice over actors. Data also support the superiority of direct versus indirect approaches for voice therapy. Further studies are needed to better identify “at-risk” subjects within this population.
