Abstract:
Background and Objectives:Patients with voice disorders often face difficulties in managing their vocal health in daily life, highlighting the need for voice management and hygiene education without temporal or spatial limitations. This study aimed to evaluate the usability of a smartphone-based voice hygiene application developed for patients with voice disorders.Materials and Method Thirty patients diagnosed with voice disorders who underwent voice therapy participated in the study. After using the voice hygiene application for 4 weeks, participants completed a usability questionnaire composed of ten items across five key categories: aesthetics, functionality, engagement, usability, and reliability (two items per category).
Results:The overall usability score of the voice hygiene application was 3.94 out of 5. The highest ratings were observed in aesthetic design and convenience. Engagement was positively influenced by the app’s reminder feature, and satisfaction regarding information reliability and system functionality was also generally high.
Conclusion:The voice hygiene application was found to be a useful tool for supporting self-management and maintaining vocal hygiene among patients with voice disorders through unrestricted accessibility. This study suggests that such applications can promote consistent voice hygiene practices and contribute to the improvement of vocal health.
