초록

이 연구의 목적은 SVM 기술에 근거한 시각 보조기에 주로 의존하는 청각 장애인을 위한 영어 모음 발음에 대한 시각 교습 방법을 제안하는데 있다. 귀로 듣기 어려운 소리로부터 SVM 기술을 사용하여 소리 특징을 추출함으로써, 각 모음의 입술 모양이 추출되었다. 모음에 대한 입술 모양의 세련미는 언어 학습자가 발음기의 움직임을 눈으로 쉽게 볼 수 있다는 점에서 유리하며, 청각 장애인을 위한 영어 모음을 학습하고 가르치는 데 유용할 것이다.

The purpose of this study is to suggest the visual teaching method for the English vowel pronunciation, especially for the hearing-impaired who mostly rely on the visual aids, based on the SVM technique. By extracting phonetic features using the SVM technique from the sounds that are hard to hear by ear, the lip shapes for each vowel were refined. The lip shape refinement for vowels is advantageous in that language learners can easily see the movement of articulators by eye, and it is helpful for learning and teaching English vowels for the hearing-impaired.
