Interactive alignment is a phenomenon whereby interlocutors adopt and re-use each other's language patterns in the course of authentic interaction. According to the interactive alignment model, originally proposed by Pickering & Garrod (2004), this linguistic coordination is one way in which interlocutors achieve understanding in dialogue, occurring at the level of the lexicon, grammar, and pronunciation. The goal of this paper is to extend this model to second language (L2) pronunciation and to discuss its possible implications for L2 pronunciation teaching.
