PURPOSE: A method for adjusting a phoneme boundary for text/speech conversion is provided to correct an error in a phoneme boundary obtained from a voice recognizing device to offer more accurate phoneme boundary information. CONSTITUTION: Phoneme information recognized by a voice recognizing device and boundary values of the phoneme information are sequentially inputted(S1), to separately detect 'voiceless consonant and vowel' and 'vowel+voiceless consonant'(S2,S3). A position where a smoothed energy variation rate represents a maximum value is controlled to be a boundary of 'consonant+vowel' or 'consonant+consonant'(S7). A position where the slope of smoothed ZCR represents a maximum value is controlled to be a boundary of 'vowel+consonant'. |
