자기주도적 중국어 성조학습을 위한 음성시각화 어플리케이션 개발 연구 = A Study on the Development of Speech Visualization Application for Self-Directed Chinese Tone Learning

다국어 초록 (Multilingual Abstract)

This study reviewed changes in the learning environment from a macro perspective and also reviewed pronunciation analysis programs which are already developed. We suggested that to develop more effective Chinese Tone learning application which can realize self-direct pronunciation learning, it should be consider two conditions: first, it should be give agile feed at anytime, second, it can be shared with others so that the learner can get more interactive feedbacks.
This paper explained the development process of Chinese Tone Learning application, which is named ‘ToneViewer’. We adopted YIN algorithm to get the pitch of native and learner’s. Then, with using GMED we compared the native and learner’s data on the Grid Metrix. The application implements basic functions such as uploading native speakers' voices, recording learners' pronunciation, and measuring the similarity between the two voices. In addition, we explained the method of subtitling briefly so that the teacher could produce subtitles for learning material.
