摘要

PROBLEM TO BE SOLVED: To suppress necessary voice data and to easily generate a voice synthesis dictionary of a target speaker of second language from voice of a target speaker of first language.SOLUTION: A voice synthesis dictionary generation device includes a mapping table generation section, an estimation section and a dictionary generation section. The mapping table generation section generates a mapping table mapping a distribution of nodes of a voice synthesis dictionary of a specific speaker of first language with respect to a distribution of individual nodes of a voice synthesis dictionary of a specific speaker of second language. The estimation section estimates a conversion matrix converting the voice synthesis dictionary of the specific speaker of the first language into a voice synthesis dictionary of a target speaker of the first language on the basis of target speaker voice of the first language, recorded sentences and the voice synthesis dictionary of the specific speaker of the first language. The dictionary generation section generates a voice synthesis dictionary of the target speaker of the second language on the basis of the mapping table, the conversion matrix and the voice synthesis dictionary of the specific speaker of the second language.SELECTED DRAWING: Figure 1
