영어 청해 교육을 위한 TTS 활용 가능성

The possibility of using TTS for teaching English listening comprehension skills

This study attempts to investigate the possibility of TTS(Text-To-Speech) for teaching English listening comprehension skills. For this purpose, about 240 middle school 2nd year students were selected as the subjects. Through 4 diagnostic tests(Listening), three similar groups(Group A, B, C) were chosen as comparative groups for the experimental tests(Listening and Dictation). The subjects took the tests, and responded to the survey about the tests. Each test was made up of two types of recorded voice. One was designed in such a way that the native speakers voice was followed by the TTS voice(Type NT) and the other was designed in the converse way(Type TN). The results of the tests were analyzed based on ANOVA. The results indicated that there are not statistically significant differences between the results of the test recorded by the Native Speakers Voice and TTS Voice. In conclusion, this study sheds light on a potential of TTS for the teaching material for listening and dictation. It suggests the more attention and continuous research for the use of TTS as a more promising educational tool in teaching English as well.
