Shadowing is a technique for enhancing second language (L2) acquisition, in which learners repeat speech aloud as they hear it, as precisely as possible, while continuing to listen attentively to the incoming speech. In the present study, we assessed the effect of speakers’ facial information (i.e. with or without the speakers’ face video including mouth movements) on the participants’ shadowing behavioral performance and fMRI brain mechanism data. As a result, it was found that (1) the shadowing reproduction rate was significantly higher in the face video condition, and that (2) the activity of "core language speech areas" such as the left inferior frontal gyrus, the left premotor cortex, the left supramarginal gyrus were more enhanced in the face video condition, based on the fMRI data analysis.
