Phonology of Exceptions For Korean Grapheme-to-Phoneme Conversion

Being an essential part of a Korean speech recognition system and a Text-To-Speech (TTS) system, a Korean Grapheme-toPhoneme conversion system is generally composed of a set of regular rules and an exceptions dictionary [1, 2, 3]. The exceptions have been recorded in the dictionary in a simple and random manner, whereas the researches on the regular rules have been actively progressed. This paper presents a systematic description of the exceptions for a Grapheme-toPhoneme conversion system based on the analysis of entries of a lexical dictionary [4] from the phonological point of view, showing that the exceptions are related with certain limited phonological phenomena.
