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.
在这项研究中，对七位女性体育教育学生教师在一个学期的学生教学中的主观和客观声音测量进行了调查。参与者在三个数据收集时间点完成了声音测量：基线、中期和学期末。声音测量包括声学和气动数据、声音质量和声音疲劳的感知评定量表、学期末问卷和嗓音障碍指数。结果表明，与基线相比，主观和客观声音测量在学期中和学期末发生了变化。声音测量的变化可能表明，发声机制正在适应教授体育教育的声音需求增加。
