Abstract(in English) | A new spectral estimation procedure which does not have interferences due to periodicity both in the time and the frequency domain is proposed. The basic form of the proposed method has only a few tunable parameters once the fundamental frequency of the signal under inspection is given. This is strong contrast to the current implementation of STRAIGHT, where many parameters were tuned numerically or in an ad hoc manner. Time domain interference is eliminated by adding power spectra that is calculated by a pair of windows that is separated one half of the fundamental period. Frequency domain interference is eliminated by combining power spectrum integration and linear interpolation based on an approximation-based interpretation of the sampling theory. The proposed method can be use to replace current spectral estimation subsystem of STRAIGHT and suitable for realtime processing. |
