The Contribution of Individual Differences to L2 Pronunciation Learning: Insights from Research and Pedagogical Implications

Abstract

Adult second language (L2) learning often exhibits great variability in its rate and outcome. Although research shows that learning trajectories are partly shaped by social and contextual factors (e.g. Larson-Hall, 2008), certain learner factors play an important role in enhancing L2 pronunciation learning by helping L2 learners notice and process input efficiently, whereas certain learner factors may impede L2 pronunciation learning by impairing attention control or slowing down L2 input processing. Therefore, in order for language teachers to provide effective instruction and help students improve their L2 pronunciation proficiency, it is beneficial for them to understand the differential impact of learner characteristics on L2 learning and adapt such understanding to their instruction and learning activities.The aim of the current article is to provide a review of existing studies that have explored individual differences (IDs) in relation to L2 pronunciation acquisition and to present implications for effective L2 pronunciation teaching. The article begins with an introduction of the paradigm shift in L2 pronunciation research and the conceptual framework of IDs proposed by Dörnyei (2009). This is followed by a summary of the processes involved in L2 pronunciation learning. The third section focuses on the characteristics of four IDs that have been found to influence the development of L2 pronunciation. Those IDs include foreign language learning aptitude (e.g. Saito and Hanzawa, 2016), musical aptitude (e.g. Milovanov et al., 2010), L2 learning motivation (e.g. Moyer, 1999), and anxiety (e.g. Baran-Łucarz, 2016). Based on the discussion in the third section, the last section will offer various applications of IDs research findings to L2 pronunciation instruction (e.g. instructional approaches, feedback, and pronunciation syllabi) for successful L2 pronunciation teaching.
