A phonological knowledge base system using unification-based formalism: a case study of Korean phonology 
 
 This paper describes the framework of a Korean phonological knowledge base system using the unification-based grammar formalism : Korean Phonology Structure Grammar (KPSG) . The approach of KPSG provides an explicit development model for constructing a computational phonological system : speech recognition and synthesis system . We show that the proposed approach is more describable than other approaches such as those employing a traditional generative phonological approach .
