Voice disorders often result from inadequate respiratory support, leading to compensatory laryngeal overuse, vocal fatigue, and deterioration in voice quality. Although traditional voice therapy emphasizes diaphragmatic breathing, it does not enhance respiratory capacity because it lacks resistance. This study aims to investigate the effects of resistance-based breathing exercises using the Expiratory Muscle Strength Trainer (EMST 150) and triflo devices on respiratory capacity, acoustic and aerodynamic voice parameters, and vocal fatigue in academics. The findings are expected to contribute to the literature and support the use of EMST as a preventive and therapeutic approach for occupational groups at risk of voice disorders.",[28,29,30,31,32],"Voice Fatigue","Voice Disorder","Academic Voice Use and Voice Fatigue","Academician's Risk of Developing Voice Disorder","Voice Disorder Prevention in Academics",[34,35,36,37,38],"Voice Disorders","Vocal Fatigue","Professional Voice Users","Respiratory Muscle Training","Acoustic Analysis","NOT_YET_RECRUITING","2026-01-19",{"date":42,"type":43},"2026-01-27","ACTUAL",{"date":45,"type":22},"2026-01-10",{"date":47,"type":22},"2026-05-10",{"name":49,"class":50},"Medipol University","OTHER"]
