Development of Japanese Dictogloss Learning Support Environment for Pronunciation Learning of Japanese Speech

Abstract

In this paper, we describe the extension of the existing pronunciation evaluation framework of Japanese dictogloss support environment. To evaluate the pronunciation in the existing environment, it was necessary for the teacher to manually create a dictionary for recognition that include incorrect pronunciation. In addition, there were few variations in the dialogue part that indicated an error in the reproduction sentence of the collaborative learner agent and the sentence of pronunciation evaluation feedback. To solve these problems, we improved the system. We evaluated the system we created and obtained the results that suggest that the proposed method is effective.
