    <Paragraph position="0"> This paper presents a new grapheme-to-phoneme conversion method using phoneme connectivity and CCV conversion rules for unlimited vocabulary Korean TTS. For the efficient conversion, new ideas of morpheme phonetic and morpheme phonetic pattern dictionary are invented and the system demonstrates remarkable conversion performance for the unlimited vocabulary texts. Our main contributions include presenting the morphologically and phonologically conditioned conversion model which is essential for morphologically and phonologically complex agglutinative languages. The other contribution is the grapheme-to-phoneme conversion model combined with the declarative phonological rule which is well suited to the given task. We also designed new CCV unit of grapheme-to-phoneme conversion for unlimited vocabulary task. The experiments show that grapheme-to-phoneme conversion performance is 97.5% in sentence conversion, and 99.9% in each grapheme conversion. We are now working on incorporating this grapheme-to-phoneme conversion into the developing TTS systems.</Paragraph>
