Frontiers of Phonology is a collection of essays that present a selective overview of recent trends in the linguistic analysis of sound structure. The essays are written by specialists from Europe, Canada and the USA and discuss issues from three broad areas of phonology: the nature and representation of phonological features; the role and structure of the skeletal tier and syllable structure; and the competing claims of derivational and declarative approaches to phonology. The book provides a forum for lively discussion of important theoretical topics from various standpoints including metrical and autosegmental phonology, government phonology, radical CV phonology, dependency phonology and declarative phonology. The contributors, who are protagonists of these different standpoints, compare notes and show the merits of their different approaches. The essays discussing derivational issues offer an excellent introduction to the area of constraints based phonology, and by covering the phonology of many languages the book provides an understanding of how human languages in general use sound. Frontiers of Phonology will be essential reading for advanced students of phonology and will also be of interest to professional linguists as well as psychologists and speech technologists.
