This handbook presents the first systematic account of corpus phonology - the employment of corpora for studying speakers'' and listeners'' acquisition and knowledge of the sound system of their native languages and the principles underlying those systems. The first part of the book discusses the design, compilation, and use of phonological corpora, while the second looks at specific applications. Part 3 presents the tools and methods used, while the final part examines a number of currently available phonological corpora in various languages. It will appeal not only to those working with phonological corpora, but also to researchers and students of phonology and phonetics more generally, as well as to all those interested in language variation, dialectology, language acquisition, and sociolinguistics.
