OBJECTIVE: Obtain aerodynamic vocal measurements of dysphonic female teachers from two groups, before and after a brief and intensive short-term voice therapy using the finger kazoo technique, compare to the respective control groups, and compare between the two study groups.
STUDY DESIGN: A randomized blind controlled clinical trial.
METHODS: A randomized blind controlled clinical trial. Measurements of maximum phonation time and sound pressure level (dB SPL) were measured before and after intensive short-term vocal therapy in 24 teachers with and without structural laryngeal disorders and 17 controls with and without structural laryngeal disorder.
RESULTS: There was significant reduction in the maximum phonation time of /e/ for the group with no structural laryngeal disorder, and a significant reduction of the maximum sound pressure level for the group with structural laryngeal disorder.
CONCLUSIONS: Based on the observed results, a significant reduction in the maximum phonation time of /e/ for the group with no structural laryngeal disorder, and a significant reduction of the maximum sound pressure level for the group with structural laryngeal disorder, it is possible that finger kazoo reduced the glottal hyperfunction by improving the balance between the respiratory and the glottal vocal production levels during speech.
