| Abstract(in English) | A Blackman window-based complementary set of time windows is proposed instead of the current implementation of STRAIGHT speech analysis, modification and resynthesis system where a complementary set of pitch synchronized Gaussian window is used to eliminate temporal variations in power spectral calculation. Gaussian window was used in the original implementation of STRAIGHT because it has the identical form in the frequency domain and has the minimum uncertainty. However, those theoretical advantages are destroyed in the process of pitch synchronization where a pitch synchronous Bartlett window is convoluted with the original Gaussian window. It is more straightforward to use cosine-based time windows instead of he pitch synchronized Gaussian window because they are intrinsically pitch synchronous. Evaluations of the proposed window set using test signals consisting of multiple harmonic components with random phase and amplitudes revealed that the proposed Blackman-base window yields the best temporal variations in resulted power spectra. |
