| 摘要 |
The present invention relates to a speech synthesizing method and apparatus based on a hidden Markov model (HMM). Among code words that are obtained by quantizing speech parameter instances for each state of an HMM model, a code word closest to a speech parameter generated from an input text using a known method is searched. When the distance between the searched code word and the speech parameter generated by the known method is smaller to or equal to a threshold value, the searched code word is output as a final speech parameter. When the distance exceeds the threshold value, the speech parameter generated by the known method is output as the final speech parameter. The final speech parameter is processed to generate final synthesized speech for the input text.
