VOICE QUALITY DIFFERENCE EVALUATION TABLE GENERATING DEVICE, VOICE QUALITY DIFFERENCE EVALUATION TABLE GENERATION SYSTEM FOR SPEECH CORPUS, AND SPEECH SYNTHESIS SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce deterioration in voice quality caused by a connection of an elementary speech unit differing in voice quality in an elementary speech unit connection type speech synthesis system. SOLUTION: A voice quality difference evaluating device 104 includes a stimulation extraction part 120 which extracts an arbitrary combination of voice data from a speech corpus 102, a stimulation presentation part 124 which generates voice stimulation according to respective pieces of voice data of the arbitrary combination extracted by the extracting means, an evaluation acquisition part 126 which derives an evaluation value regarding a difference in voice quality between the voice data of the combination by conducting a perception test regarding an auditory difference in voice quality from the voice stimulation, and a table generation part 128 which stores the evaluation value representing the difference in voice quality between the voice data of the combination according to the result of the perception test while making it correspond to the combination of voice data and generates a voice quality difference evaluation table 108.
