First published in 1991. In this study, the author investigates the proper treatment of harmony processes in phonological theory. The data examined lead to a formulation of morphologically governed harmony processes which involves multi-planar representations. The analysis of multi-planar harmony leads into a discussion of Plane Conflation and Bracket Erasure in Lexical Phonology. This title will be of great interest to students of linguistics.

This volume is a collection covering the diverse areas of psycholinguistics, syntax, computational linguistics and phonology. Abney's paper on Chunks provides an interesting new approach to phrase structure, motivated by psycholinguist data, something that is rarely done. Berwick and Fong provide a history of computational implementations of (Chomskyan) Transformational Grammar. Cole's phonology paper, arguing from Chamorro and English stress that cyclicity is not needed in phonology, is also preceded by a one-and-a-half-page introduction on why this is relevant to computation. Coleman's contribution summarises work on computational phonology and describes the York Talk speech synthesis system. Hirschberg and Sproat's paper describes a system they have written to assign pitch accent to unrestricted text in an RT&T text-to-speech system. This is very much applied natural language processing, but their system represents a more thorough-going attempt at doing this well than has been previously attempted, and this appears to be the first write-up of this work. Johnson and Moss introduce Stratified Feature Grammar, a formal model of language, inspired by Relational Grammar but formalised by using and extending tools developed in the unification grammar community. Finally, Nakazawa extends further Tomita's work so that computer science LR parsing methods can be applied to natural language grammars, here feature-based grammars.

The papers in this volume address a range of issues and problems in current phonological theory, examining many levels of phonological representation. The papers grew out of a conference held in May, 1991, at the University of Illinois at Urbana-Champaign, in celebration of the twenty-fifth anniversary of the Department of Linguistics. The goal of the conference was to provide a forum for the discussion of some of the leading ideas and innovations in phonology today. Over one hundred researchers and students participated in presentations and lively debate. The conference imposed no single theme under which all of the papers were organised.
