In recent years, shadowing has been garnering attention in Japanese language education. It has been shown that by introducing shadowing in classroom instruction, the speech perception, pronunciation, and listening comprehension ability of language learners can be improved. Japanese (the geminate consonant, the long sound) are considered difficult for native Chinese speakers at the beginner and intermediate levels. This study examined whether learners' skills in perception and production of Japanese special phonemes can be improved through shadowing practice. The investigation was carried out over the course of three months among eight Japanese language learners from a Chinese L1 background. The study investigated the improvement of the perception and production of assimilated and long sounds in vocabulary and basic sentence learning. The improvement period and changes were also investigated. According to the results of the pretest, posttest, as well as the delayed posttest, it was found that the production of both assimilated and long sounds improved slightly. Delayed posttest results indicate that the improvement was maintained at a comparatively high level, suggesting that the positive effects of shadowing practice may be long term.
