This article presents the fundamentals of descriptive phonology and gives an overview of computational phonology. Phonology is the systematic study of sounds used in language, and their composition into syllables, words, and phrases. It introduces some of the key concepts of phonology by simple examples involving real data and gives a brief discussion of early generative phonology. It analyses the autosegmental phonology using some data from African tone language. This article considers in detail one level of phonological hierarchy, namely, the syllable. It reveals many interesting issues...

This article presents the fundamentals of descriptive phonology and gives an overview of computational phonology. Phonology is the systematic study of sounds used in language, and their composition into syllables, words, and phrases. It introduces some of the key concepts of phonology by simple examples involving real data and gives a brief discussion of early generative phonology. It analyses the autosegmental phonology using some data from African tone language. This article considers in detail one level of phonological hierarchy, namely, the syllable. It reveals many interesting issues that are confronted by phonological analysis. Some of these theoretical frameworks include: lexical phonology, underspecification phonology, government phonology, declarative phonology, and optimality theory. The article provides a means for phonological generalizations such as rules and constraints to give a finite-state interpretation.
