학문 목적 한국어 말하기 수업에서의 음성합성기술(TTS) 활용 사례 연구

A Case Study on the Use of Speech Synthesis Technology(TTS) in Korean Speaking Class for Academic Purpose: Focusing on Presentation Tasks.

The purpose of this study is to apply the TTS(Text-to-Speech) program to the field of Korean language education and to improve presentation skills by leading input/output activities. In this study, learners’ perceptions were examined through a survey after using listening material produced by the TTS program in intermediate Korean speaking classes for foreign students. The Korean speaking class focused on presentation. In the class, the presentation written by the learner was produced as a listening material using the TTS program and distributed to the students. It also induced input/output tasks by presenting students with tasks to record after listening to the listening material and practicing presentation. At the end of the semester, the final composition written by the students was produced as listening material and distributed to provide a model for pronunciation practice. As a result, it was confirmed that the use of TTS program in academic speaking classes provided sufficient input/output opportunities for students to learn Korean speaking and listening. However, it was confirmed that the task of improving the performance of TTS programs remained to produce listening material close to natural languages.
