Abstract(in English) | In concatenative speech synthesis, the naturalness of synthetic speech is affected by various factors. A cost for segment selection is calculated by integrating some sub-costs capturing the degradation of naturalness caused by such factors. In this paper, we optimize each sub-cost function for converting a feature into a sub-cost based on perceptual evaluations. Test sets for evaluating sub-costs are constructed by controlling variations of sub-costs to focus on each sub-cost to be evaluated. We clarify the effectiveness of optimizing sub-cost functions based on perceptual evaluations from a result of a preference test comparing synthetic speech before optimizing sub-cost functions with that after optimizing sub-cost functions. |
