Twenty-nine participants with voice disorders who are working in a hospital and who are using their voice for more than 4 hours per day were recruited.

• Study group: EMST 3 days per week and involved performing 25 expiratory exercises (five cycles, each comprising five breaths) for 5 weeks
• Control group: NO intervention
• All participants underwent aerodynamics analysis, pulmonary function, MEP (Maximum Expiratory Pressure), and completed a vocal symptoms questionnaire before and after
