'A comprehensive book on L2 speech is long overdue and these authors exceed all expectations in terms of quality. This volume will forge a new generation of knowledgeable, well-trained scholars.' Barbara E. Bullock, University of Texas, Austin

'This book combines a well-organized and reader-friendly overview of research on non-native speech with skilfully designed guidance on how to conduct this research. I recommend it as a great resource for anyone, student or teacher, who wants to understand or conduct research on second language speech.' Ocke-Schwen Bohn, Aarhus University

'Colantoni, Steele and Escudero are to be commended for demonstrating that the study of second language speech is not an esoteric academic niche but rather a rich, complex epistemological enterprise necessarily informed by linguistic theory and psycholinguistic method. In this valuable book, they have articulated how a wide swathe of our current knowledge in the field has been constructed, and how we (both current and future researchers) need to proceed to create new knowledge.' John Archibald, University of Victoria
