Abstract This article analyses how ChatGPT may be used in L2 pronunciation teaching and learning, especially when explicit pronunciation instruction is integrated into a communicative approach to language teaching. The possible use of ChatGPT for production practice, listening practice, and obtaining explanations and examples of target L2 features is discussed and exemplified. Limitations of the tool for pronunciation work are also discussed alongside some challenges that L2 learners and L2 teachers may face when using the tool. The article concludes that ChatGPT may be incorporated into teachers’ and learners’ array of technology tools for teaching or learning L2 pronunciation. However, ChatGPT should be regarded as a complementary tool to other pronunciation teaching and learning resources. Above all, ChatGPT cannot replace interaction through formal instruction with teachers and other L1 or L2 speakers of English in the development of L2 pronunciation.
