Method for text-to-pronunciation conversion capable of increasing the accuracy by re-scoring graphemes likely to be tagged erroneously |
摘要 |
The present invention provides a method for text-to-pronunciation conversion capable of increasing the accuracy by re-scoring graphemes likely to be tagged erroneously. Grapheme segmentation and phoneme tagging are first applied to an input word to generate at least one grapheme-phoneme pair sequence, and the score of each grapheme-phoneme pair sequence is also computed. Then, at least one grapheme-phoneme pair sequence having a higher score is selected. For the selected grapheme-phoneme pair sequence that has a grapheme likely to be tagged erroneously, the features in the context of the grapheme are selected and made good use of computing re-score corresponding to the graphemes likely to be tagged erroneously, so as to re-score the grapheme-phoneme pair sequence. Accordingly, the grapheme-phoneme pair sequence with the highest score is the final conversion result.
