Abstract

This study focused on the changes in the voices in determining the effects of speech training. This study aimed to make more visible and scientific evaluation of the changes in the voices among the substantial effects obtained from speech training. As a result, some objective differences from before the speech training could be found in the voice of every learner. Each learner showed gradual technical improvement in a variety of vocal elements, including resonance and timbre, accuracy of pronunciation, pause; that is, the voice became more powerful, more accurate pronounced, more pausing and more stable than before the speech training. This study determined if speech training could change a voice and the results are expected to help speech learners participate actively in speech training and see their speech ability improved.

본 연구는 스피치교육의 효과를 측정하는데 있어 화자의 목소리의 변화에 주목하였다. 본 연구에서는 스피치교육을 통해 얻게 되는 실질적 효과 중 목소리의 변화를 보다 가시적이고, 과학적으로 평가하고자 하였다. 연구결과 모든 학습자의 목소리에서 스피치교육 전과는 다른 객관적인 변화를 찾을 수 있었다. 학습자 모두 공명, 음색, 발음의 정확성, 휴지 등 다양한 목소리 요소에서 점진적 기술향상이 이루어졌다. 즉, 스피치교육을 받기 전보다 목소리가 풍부해지고 발음이 정확하고, 휴지를 잘 활용하는 안정화된 결과를 볼 수 있었다. 이 연구결과를 통해 스피치훈련을 통해 목소리의 변화가 나타날 수 있는지 분석하고, 스피치 학습자들이 스피치교육에 적극 임해 스피치실력 향상의 결과를 얻을 수 있을 것으로 기대된다.
