Morphological analysis method and apparatus used in text-to-speech synthesizer

摘要

The present invention relates to, in particular, morphological analyzer and a method used by the document analyzer of the speech synthesizer, relates to a speech synthesizer.; Document analyzer according to the present invention is subjected to the pronunciation information and document pre-processing user dictionary application stage, special pattern processing steps, as well as statements extracted to provide language information to the speech synthesizer properly respond to multiple document types.; In the present invention, instead of using frequency information lexical probability and the contextual probability to increase the accuracy of the morphological analysis and part of speech tagging and uses the connection weighting rule and the expanded right and left connection information, morphological analysis error correction knowledge. In addition, the candidate list stemming POS is integrated into one list and morphological analysis of the same type to play a similar role at creation optimizes the morpheme candidate list by not created.
