VOICE PITCH MARK SETTING DEVICE, VOICE SYNTHESIZER, VOICE PITCH MARK SETTING METHOD, AND VOICE SYNTHESIZING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a voice pitch mark setting device and a voice pitch mark setting method that can improve the quality of a synthesized voice by text voice synthesis, and to provide a voice synthesizer and a voice synthesizing method that use the voice pitch mark setting device and voice pitch mark setting method. PSOLUTION: A plurality of sets of pitch mark candidates set for an elementary speech unit are used and modification parameter values of the elementary speech unit are controlled according to modulation parameter values of a training elementary speech unit to generate a plurality of synthesized elementary speech units corresponding to the plurality of sets of pitch mark candidates. Distortions of the plurality of synthesized elementary speech units are evaluated and a pitch mark is set based upon evaluation results. PCOPYRIGHT: (C)2008,JPO&INPIT
