This volume is a collection of 13 chapters, each devoted to a particular issue that is crucial to our understanding of the way learners acquire, learn, and use an L2 sound system. In addition, it spans both theory and application in L2 phonology. The book is divided into three parts, with each section unified by broad thematic content: Part I, "e;Theoretical Issues and Frameworks in L2 Phonology,"e; lays the groundwork for examining L2 phonological acquisition. Part II, "e;Second Language Speech Perception and Production,"e; examines these two aspects of L2 speech in more detail. Finally, Part III, "e;Technology, Training, and Curriculum,"e; bridges the gap between theory and practice. Each chapter examines theoretical frameworks, major research findings (both classic and recent), methodological issues and choices for conducting research in a particular area of L2 phonology, and major implications of the research findings for more general models of language acquisition and/or pedagogy.
