METHOD FOR RULE SPEECH SYNTHESIS

摘要

PROBLEM TO BE SOLVED: To provide a method for rule speech synthesis whereby speech synthesis is performed by utilizing CVs and speech elements in a VC unit prepared beforehand and whereby a speech dictionary volume and distortion in a connection plane are reduced. SOLUTION: The method for rule speech synthesis in this invention is characterized by dividing CVs and speech elements in a VC unit into synthesis units smaller than phoneme units by using HMnet, creating an intra-phoneme network over all the synthesis units, and selecting speech elements corresponding to an input phoneme train on the basis of the obtained intra-phoneme network.
