Abstract

ObjectiveThe main purpose of this study is to investigate the effectiveness of a 12-week holistic vocal training program designed for theatre students. MethodsThe 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. ResultsWithin-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. ConclusionIt 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.
