Voice characteristics of female physical education student teachers.

In this study, the subjective and objective voice measures of seven female physical education student teachers during a semester of student teaching were investigated. The participants completed the voice measures at three data collection time points: baseline, middle, and end of the semester. The voice measures included acoustic and aerodynamic data, perceptual rating scales of vocal quality and vocal fatigue, an end-of-semester questionnaire, and the Voice Handicap Index. Results demonstrated that the subjective and objective voice measures changed at the middle and the end of the semester as compared with those at baseline. The change in the voice measures may suggest that the vocal mechanism was adapting to the increased vocal demands of teaching physical education.
