Compared to low-variability training, high-variability training leads to better learning outcomes and supports generalization of learning. However, it is unclear whether the learning advantage is driven by multiple talkers or by enhanced acoustic variability across target sounds. The current study addressed this issue in nonnative production…

We propose a new framework for conceptualizing measures of instructed second language (L2) pronunciation performance according to three sets of parameters: (a) the constructs (focused on global vs. specific aspects of pronunciation), (b) the scoring method (human raters vs. acoustic analyses), and (c) the type of knowledge elicited (controlled vs.…

Children who start formal education in a second language may experience slower vocabulary growth in that language and subsequently experience disadvantages in literacy acquisition. The current study asked whether lexical specificity training can stimulate bilingual children's phonological awareness, which is considered to be a precursor to…

Sixty-five Japanese learners of English participated in the current study, which investigated the acquisitional value of form-focused instruction (FFI) with and without corrective feedback (CF) on learners' pronunciation development. All students received a 4-hr FFI treatment designed to encourage them to notice and practice the target feature of…

Learning the Chinese tone system is a major challenge to students of Chinese as a second or foreign language. Part of the problem is that the spoken Chinese syllable presents a complex perceptual input that overlaps tone with segments. This complexity can be addressed through directing attention to the critical features of a component (tone in…
