DEVICE, METHOD, AND PROGRAM FOR SPEECH SYNTHESIS

摘要

PROBLEM TO BE SOLVED: To provide a speech synthesizer efficiently synthesizing a natural speech of high quality. SOLUTION: The speech synthesizer is provided with: an acquiring means 110 of acquiring a meter series for a target speech to be synthesized for a plurality of segments respectively; merged speech element holding means 160 and 170 of holding merged speech elements obtained by merging a plurality of speech elements and merged speech element meter information showing meters of the merged speech elements while making them correspond to each other; a held speech distortion estimating means 130 of estimating the degree of distortion between segment meter information showing meters of segments obtained by the acquiring means 110 and the merged speech element meter information held in the merged speech element holding means 160 and 170; a merged speech element selecting means 140 of selecting a merged speech element on the basis of the degree of distortion estimated by the held speech distortion estimating means 130; and a speech synthesizing means 150 of generating a synthesized speech by connecting respective merged speech elements that the merged speech element selecting means 140 select for the respective segments.
