This study investigated how Japanese learners of Japanese as a second language learn pronunciation in Japanese using a shadowing application, with a focus on the effect of shadowing on improving intonation and accent specifically. Thirty-eight participants used a shadowing application individually without explicit instruction. After the experiment, a broad range of F0 movements were observed in participants' speech, which suggests that the characteristics of Japanese intonation (e.g. henoji intonation) can be learned through shadowing.
