Abstract

Hearing - impaired children who have difficulty hearing and hearing go through pronunciation training. The purpose of this study is to provide the pronunciation training system based on digital contents that can be used for repeated hearing training while maintaining interest in hearing - impaired children. For this purpose, we conducted an interview survey for users and experts. Based on the results, we developed a digital content based pronunciation training system. Finally, to verify the effect of the digital service implemented, the user test was conducted for the hearing - impaired children. As a result of the interview, repeated training and interest factors were found to be essential factors affecting pronunciation training. In implementing digital services, we have used fairy tales and a variety of interactive elements to derive children's interests and designed a user flow that can train multiple words and sentences for effective repetition training. As a result of the test, this digital content was evaluated positively.

듣고 말하는 어려움이 있는 청각장애 아동은 원활한 의사소통을 위해 긴 시간 동안 청력 훈련인 조음 훈련 과정을 거친다. 본 연구의 목적은 청각장애 아동을 대상으로 흥미를 유지하며 반복적인 청력 훈련을 할 수 있는 디지털 콘텐츠 기반의 조음훈련시스템을 제공하는 것이다. 이를 위하여 우선 사용자와 전문가를 대상으로 인터뷰 조사를 진행하였고, 이 결과를 바탕으로 디지털 콘텐츠 기반의 조음훈련 서비스를 개발하였다. 마지막으로 앞서 구현된 디지털 서비스의 훈련 효과를 검증하기 위하여, 청각 장애 아동을 대상으로 사용자 테스트를 진행하였다. 인터뷰 분석 결과, 조음훈련에 영향을 미치는 중요 요인으로 반복훈련과 흥미 요인이 도출되었다. 디지털 서비스를 구현하는데 있어서, 아동들의 흥미 도출을 위해 동화와 다양한 인터랙션 요소를 활용했고, 효과적인 반복훈련을 위해 복수의 단어와 문장을 훈련할 수 있는 사용자 흐름을 설계하였다. 개발된 서비스에 대한 청각장애 아동의 테스트 결과, 본 디지털 콘텐츠는 조음 훈련의 효과와 흥미에 대하여 긍정적으로 평가되었다.
