This volume explores a variety of aspects of second language speech, with special focus on contributions to the field made by (primarely) generative linguists looking at the sounds and sound systems of second language learners. Second Language Phonology starts off with an overview of second language acquisition research in order to place the study of L2 speech in context. This introductory chapter is followed by an outline of traditional approaches to investigating interlanguage phonology. The third chapter consists of a discussion of relevant aspects of a learning theory that must be included in a treatment of how people learn sound systems. The next three chapters focus on particular aspects of the mental represenation of phonological competence; segments, syllables, and stress, respectively. The penultimate chapter deals with issues related to the mechanisms that govern the changing of interlanguage grammars over time. The volume ends with a summary of the issues raised throughout the text.
