The main purpose of this study is to investigate the effectiveness of a 12-week holistic vocal training program designed for theatre students.
The participants included 10 female and 8 male students, who were third- and fourth-year students of a state conservatory theatre department. Participants randomly selected from among those who were between the ages of 18-30 years, had no history of voice disorders, and had no systemic and neurological disorders. The study group (n = 9) was involved in the vocal training program. The control group (n = 9) has not received any training. During the program, 12 sessions of lectures and voice exercises were given to all participants of the study group for a period of 12 weeks. The sessions were planned to last for a duration of 30-45 minutes. Participants' knowledge of vocal health was assessed using a questionnaire that was developed in the present study and a multidimensional voice assessment protocol including acoustic analyses and audio-perceptual evaluation has been applied.
Within-group comparisons indicated a significant increase in the study group participants' knowledge of vocal hygiene after training (P = 0.011). Similarly, the study group outperformed the control group in the vocal mechanism knowledge (P = 0.027). Multidimensional Voice Profile findings revealed that vocal qualities of the control group deteriorated, whereas no alterations were found in the study group. Audio-perceptual analysis conducted through the Consensus Auditory-Perceptual Evaluation of Voice did not introduce significant changes in the control group in overall severity and roughness parameters, these values were found significantly improved for the study group.
It can be concluded that the Holistic Vocal Training Program designed in the present study is effective for preserving theatre students' vocal health and voice quality. It is important for future studies to search the long-term effects.
本研究的主要目的是调查为戏剧专业学生设计的为期12周的整体声乐训练计划的有效性。
参与者包括10名女生和8名男生，他们是一所国立音乐学院戏剧系的三、四年级学生。参与者从年龄在18至30岁之间、无嗓音疾病史、无全身及神经系统疾病的学生中随机选取。研究组（n = 9）参与声乐训练计划。对照组（n = 9）未接受任何训练。在该计划期间，研究组的所有参与者接受了为期12周的12次讲座和嗓音练习。每次课程计划持续30至45分钟。使用本研究编制的问卷评估参与者的嗓音健康知识，并应用了包括声学分析和听觉-感知评估在内的多维度嗓音评估方案。
组内比较表明，训练后研究组参与者的嗓音卫生知识有显著增加（P = 0.011）。同样，研究组在发声机制知识方面的表现优于对照组（P = 0.027）。多维度嗓音剖面图结果显示，对照组的嗓音质量恶化，而研究组未发现变化。通过嗓音共识听觉-感知评估进行的听觉-感知分析未发现对照组在总体严重程度和粗糙度参数方面有显著变化，而研究组的这些值有显著改善。
可以得出结论，本研究设计的整体声乐训练计划对保护戏剧专业学生的嗓音健康和嗓音质量有效。未来的研究探索其长期效果很重要。
