Abstract

A robot's recognition and diagnosis of pronunciation and its speech are the most important interactions in RALL(Robot Assisted Language Learning). This study is to verify the effectiveness of robot TTS(Text to Sound) technology in assisting Korean English language learners to acquire a native-like accent by correcting the prosodic errors they commonly make. The child English language learners' F0 range and speaking rate in the 4th grade, a prosodic variable, will be measured and analyzed for any changes in accent. We compare whether robot with the currently available TTS technology appeared to be effective for the 4th graders and 1st graders who were not under the formal English learning with native speaker from the acoustic phonetic viewpoint. Two groups by repeating TTS of RALL responded to the speaking rate rather than F0 range.

로봇의 발음인식과 진단 그리고 발음빠르기는 로봇보조언어교육의 가장 중요한 상호작용이다. 이 연구는 한국인 초등 영어 학습자를 위하여 음율적 오류를 수정함으로써 원어민과 같은 억양을 산출하기 위한 로봇음성합성기의 효과성을 측정하기 위한 것이다. 이를 위해 초등 4학년 영어학습자들의 F0 범위값과 발화 속도라는 음성음향적 변수를 측정하여 분석하였고, 그 결과를 정규 영어교육의 시작하지 않은 1학년 학습자와 비교하였다. 로봇음성합성기를 활용한 언어학습에서 두 집단은 F0값보다 발화속도 변인에 반응하였다.
