Results of the investigators' previous work showed that mask-wearing healthcare workers have difficulty with voice and communication. Healthcare workers reported significant increases in vocal effort and dyspnea while wearing masks, and showed greater effort and poorer vocal quality at the end of the workday compared to the beginning of the day. Despite these negative changes, very few healthcare workers reported using any type of communication strategy (e.g., taking breaks, using gestures). Therefore, the investigators developed educational modules to address the voice and communication problems facing this population. This clinical trial plans to evaluate how these educational modules impact subjective/objective voice and communication measures in mask-wearing healthcare workers.
