PURPOSE:To provide a speech rule synthesizing device which can output a synthesized speech with high articulation and naturalness by selecting element pieces which are relatively small in arithmetic quantity and also have small spectrum distortion at an element piece connection part from a large amount of speech data. CONSTITUTION:This device is equipped with a speech parameter file 16 which contains speech synthesis parameters labeled, at every phoneme, by analyzing a natural speech, a synthesis unit setting part 14 which sets information in the unit of proper synthesis so as to compose an output speech, a target spectrum calculation part 15 which calculates a target spectrum at a connection part 18 in the synthesis unit on the basis of phoneme information, rhythm information, and the information set at the synthesis unit setting part 14, a synthesized element piece selection part 17 which selects proper synthesized element pieces from speech synthesis parameters stored in the speech parameter file 16 on the basis of the target spectrum calculated by the target spectrum calculation part 15, and a synthesized element piece connection part 18 which connects the synthesized element pieces selected by the synthesized element piece selection part 17. |
