Voice Disorders Clinical Trial
Official title:
Virtual Reality in Teachers' Vocal Motor Behavior Acquisition (VirtuVox): Randomized Controlled Trial
Scientific literature supports that teachers are at greater risk for voice disorders than the
general population. In the classroom, the teacher's voice represents the main communication
tool. Optimal voice use is indispensable to ensure effective teaching and preserve the
teacher's vocal health.
This project investigates how virtual reality (VR) facilitates the learning of effective
vocal skills and their application in real-world contexts. Based on acoustic analyses and
self-assessment scales, the investigators compare 100 future teachers randomly assigned in
two groups. The experimental group (n=50) receives a voice training by VR simulations and
voice information. The control group (n=50) only receives voice information.
Experimental group participants receive direct method (three 1-hour sessions of voice training by virtual reality simulations over a course of 3 weeks) and indirect method (one 1-hour session of information on voice function and voice hygiene). Control group participants receive indirect method (one 1-hour session of information on voice function and voice hygiene). ;
