CROSS LINGUAL VOICE SYNTHESIS MODEL LEARNING DEVICE, CROSS LINGUAL VOICE SYNTHESIS DEVICE, CROSS LINGUAL VOICE SYNTHESIS MODEL LEARNING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a cross lingual voice synthesis technology which can synthesize voice in a language to be synthesized by a target speaker even when there is only one person's voice data in the language to be synthesized that is not voice data of the target speaker.;SOLUTION: There are provided: a time information adjustment part 101 which generates after time information adjustment target speaker voice data _n and after time information adjustment learning target language voice data _n from target speaker voice data and learning target language voice data _n; a vocal quality converter learning part 103 which learns a non-specific speaker vocal quality converter from a set of the after time information adjustment target speaker voice data _n and the after time information adjustment learning target language voice data _n; a vocal quality conversion part 111 which uses the non-specific speaker vocal quality converter to generate after vocal quality conversion language to be synthesized voice data having a target speaker's vocal quality from the language to be synthesized voice data; and a synthesis model learning part 113 which learns a cross lingual voice synthesis model from the after vocal quality conversion language to be synthesized voice data and a set of the language to be synthesized speech information.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
