Abstract
Japanese animation called "Japanimation" is highly regarded for its artistry. Many people abroad are interested in Japan through animes and start learning Japanese and listening practice. We focused on the possibility of using animes as teaching materials for listening practice. An episode of anime contains not only one conversation but also several partial conversations. Since the words and expressions in each partial conversation are different, the degree of difficulty might also be different. This paper proposes a method to estimate the degree of difficulty of the partial conversation of anime. By providing partial conversations with estimated levels, we support learners in their listening practices. In evaluation experiments, participants were asked to take a pre-test, practice their listening with the degree assigned partial conversations, and take a post-test. The participants were divided into two groups. An experimental group used the degree set partial conversations while a control group used just partial conversations for their listening exercises. The experimental results showed that the increase in correct rate between pre-test and post-test was 26.4% in the experimental group of L2 of JLPT while that was 10.6% in the control group.
