Probabilistic phonology

Abstract

AbstractProbability and frequency are becoming increasingly important in phonological analysis. This article reviews contemporary perspectives on how phonological theory addresses gradient phonological patterns shaped by probability and frequency, drawing on theories of the lexicon, grammar, and statistics. After examining their motivations, we show how these diverse theoretical perspectives have been applied to a variety of problems in core phonology, including phonotactics, morphophonology, sound change, phonological categorization, and language development. Our review of theory and applications supports a growing consensus in the field that phonological theories must reckon with probability. Our review also identifies problems stemming from a lack of cohesion in the field, and suggests potential solutions to these problems.
