에스틸 보이스 트레이닝(Estill Voice Training) 훈련이 배우의 음성 공명 개선에 미치는 영향: EVT를 적용한 실험 분석 사례를 중심으로

초록

Actors should be able to resonate voice with an understanding of how the voice sounds and how it is transmitted in specific space. Particularly understanding the nature of resonance in voice can be a means to enhance the effectiveness of dialogue delivery. The vocal training models for actors vary widely, ranging from the established Bel Canto technique developed in the 18th century to Seth Riggs's Speech Level Singing (SLS), Cicely Berry's Voice Work, the Alexander Technique, and Estill Voice Training (EVT). Among them, one vocal model that can provide objective evidence regarding resonance training and its effects is Estill Voice Training (hereafter EVT). The characteristics of the EVT model, derived through the preliminary research by the researcher, are as follows. Firstly, EVT involves simultaneous visual, auditory, and kinesthetic senses, al - lowing analysis from various perspectives. Secondly, such training with multiple senses concurrently mini - mizes misunderstandings and confusion regarding the voice, leading to a shortened practice period. The re- searcher judged that, based on these characteristics, EVT could be utilized to improve vocal resonance. This study involves the process and conclusion of utilizing the EVT model as a training tool to en- hance the vocal resonance of actors. To improve resonance, basic knowledge is required about how sound is generated, how it is controlled by which muscles, and how sound is heard and perceived. Therefore, participants in the study focused on training to separate and control larynx structures re- lated to resonance after initiating their learning about the principles of voice production. Throughout the training process, their voices were objectively recorded and analyzed. The research results confirmed that the independent control of two laryngeal structures was specifically improved for all participants. In conclusion, participants gained the ability to selectively use their desired vocal tones by fulfilling proper movements of the velum and aryepiglottic sphincter(AES), contributing to the functionality of resonance. The researcher concluded that the EVT model, based on vocal science, will play a crucial role as an effective vocal technique in shortening actors' vocal training periods in the future.
