| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Mixed-mode excitation is crucially important and effective for high-quality speech analysis, modification and resynthesis systems. However, there are several incompatible constraints in representation and estimation of aperiodic component in the mixed-mode excitation. The current implementation of aperiodic component provides an answer for estimation problem at the expense of complicated representation which prevents ease of applications. This article proposes an aperiodic component spectral model that consists of exponential nonlinearity and a sigmoid. Although the proposed model is still in a preliminary phase and needs verifications based on variety of speech sounds, the proposed model seems to represent aperiodic components in a highly efficient manner. Informal listening tests also suggested that the proposed model provides better synthesized speech quality. | |
