"In phonological theory, sonority is crucial, perplexing, and controversial. PArker's book is the most comprehensive and detailed examination of sonority to date, and is without doubt a significant waypoint in understanding this crucial aspect of linguistic cognition."Paul de Lacy of Rutgers University "As a property that spans the entire gamut of speech sounds, sonority has been a key component in explanations of phonotactics and prosody. THe papers in this volume explore sonority from a variety of perspectives (articulatory and acoustic phonetic, formal phonological, lexical statistical) and raise our understanding of this pervasive yet elusive feature to a new level."Michael Kenstowicz of MIT (Massachusetts Institute of Technology).
