To what extent do complex phonological patterns require the postulation of universal mechanisms specific to language? In this volume, we explore the Emergent Hypothesis, that the innate language-specific faculty driving the shape of adult grammars is minimal, with grammar development relying instead on cognitive capacities of a general nature. Generalisations about sounds, and about the way sounds are organised into meaningful units, are constructed in a bottom-up fashion: As such, phonology is emergent. We present arguments for considering the Emergent Hypothesis, both conceptually and by working through an extended example in order to demonstrate how an adult grammar might emerge from the input encountered by a learner. Developing a concrete, data-driven approach, we argue that the conventional, abstract notion of unique underlying representations is unmotivated; such underlying representations would require some innate principle to ensure their postulation by a learner. We review the history of the concept and show that such postulated forms result in undesirable phonological consequences. We work through several case studies to illustrate how various types of phonological patterns might be accounted for in the proposed framework. The case studies illustrate patterns of allophony, of productive and unproductive patterns of alternation, and cases where the surface manifestation of a feature does not seem to correspond to its morphological source. We consider cases where a phonetic distinction that is binary seems to manifest itself in a way that is morphologically ternary, and we consider cases where underlying representations of considerable abstractness have been posited in previous frameworks. We also consider cases of opacity, where observed phonological properties do not neatly map onto the phonological generalisations governing patterns of alternation.

Using detailed analyses of cross-generational case studies, Smith explains the acquisition of language phonology by children.

This collection of recent papers in Laboratory Phonology approaches phonological theory from several different empirical directions. Psycholinguistic research into the perception and production of speech has produced results that challenge current conceptions about phonological structure. Field work studies provide fresh insights into the structure of phonological features, and the phonology-phonetics interface is investigated in phonetic research involving both segments and prosody, while the role of underspecification is put to the test in automatic speech recognition.

How well have classic ideas on whole-word phonology stood the test of time? Waterson claimed that each child has a system of their own; Ferguson and Farwell emphasized the relative accuracy of first words; Menn noted the occurrence of regression and the emergence of phonological systematicity. This volume brings together classic texts such as these with current data-rich studies of British and American English, Arabic, Brazilian Portuguese, Finnish, French, Japanese, Polish and Spanish. This combination of classic and contemporary work from the last thirty years presents the reader with cutting-edge perspectives on child language by linking historical approaches with current ideas such as exemplar theory and usage-based phonology, and contrasting state-of-the-art perspectives from developmental psychology and linguistics. This is a valuable resource for cognitive scientists, developmentalists, linguists, psychologists, speech scientists and therapists interested in understanding how children begin to use language without the benefit of language-specific innate knowledge.

The Routledge Handbook of Phonological Theory provides a comprehensive overview of the major contemporary approaches to phonology. Phonology is frequently defined as the systematic organisation of the sounds of human language. For some, this includes aspects of both the surface phonetics together with systematic structural properties of the sound system; for others, phonology is seen as distinct from, and autonomous from, phonetics. The Routledge Handbook of Phonological Theory surveys the differing ways in which phonology is viewed, with a focus on current approaches to phonology. Divided into two parts, this handbook: covers major conceptual frameworks within phonology, including: rule-based phonology; Optimality Theory; Government Phonology; Dependency Phonology; and connectionist approaches to generative phonology; explores the central issue of the relationship between phonetics and phonology; features 23 chapters written by leading academics from around the world. The Routledge Handbook of Phonological Theory is an authoritative survey of this key field in linguistics, and is essential reading for students studying phonology.
