| Topic-020: Generative Phonology Like other areas of grammar, a major change in the theory of phonology came about in the s when many people became convinced that important facts about the sound systems of languages were being missed by phonologists who concentrated solely on the identification of phonemes and the analysis of relationships between them. Morris Halle and Noam Chomsky showed that there were many sound processes which, while they are observable in the phonology, are actually regulated by grammar and morphology. This area of phonology is mainly related to specific phonological rules within languages. These rules describe how they work and regulate changes such as substitutions, deletions and insertions of Copyright Virtual University of Pakistan Phonetics and Phonology (ENG) VU sounds in specific contexts. In order to highlight these phonological rules, an elaborate method of writing in an algebra-like style was evolved this can be seen in the best known generative phonological treatment of English (The Sound Pattern of English by Chomsky and Halle, 1968). This type of phonology became extremely complex it has now been largely replaced by newer approaches to phonology, many of which, despite rejecting the theory of the Sound Pattern of English, are still classed as generative since they are based on the principle of an abstract, underlying phonological representation of speech which needs rules to convert it into phonetic realizations. Following are the theories that have stemmed from generative phonology • Autosegmental phonology • Metrical phonology • Lexical phonology • Optimality theory Download 1.01 Mb.
