This paper describes a grapheme-to-phoneme conversion method using phoneme connectivity and CCV conversion rules. The method consists of mainly four modules including morpheme normalization, phrase-break detec- tion, morpheme to phoneme conversion and phoneme connectivity check. The morpheme normalization is to replace non-Korean symt)ols into standard Korean graphemes. The phrase-break detector assigns phrase breaks using part-of-speech (POS) information. In tile mort)heme-to-phoneme conversion module, each morpheme in the phrase is converted into phonetic t)atterns by looking up the morpheme phonetic pat- tern dictionary which contains candidate phonological changes in boundaries of the morphemes. Graphemes within a morpheme are grouped into CCV patterns and converted ...
