This paper proposes a grapheme to phoneme conversion method for Korean Text-to-Speech system where the phonological phrasing information is incorporated. To verify the validity of the proposing method, a hybrid approach based grapheme to phoneme conversion system, which combines hand-written morphophonemic rules and maximum entropy models, is implemented. The experimental results show that the prediction accuracy of tensification on the eojeol (a space-delimited orthographic word) boundaries improve from 93.20% to 95.45%, which leads to better overall grapheme to phoneme conversion performance.
