| Abstract(in English) | We propose two algorithms to calculate interference-free power spectra of periodic signals. This set of algorithms is our fourth reinvention of interference-free power spectral representations for legacy-STRAIGHT, TANDEM-STRAIGHT, and CheapTrick, 20, 10, and three years ago, respectively. The first method directly calculates the interference-free spectrogram using the one-stage procedure. The next method calculates an interference-free power spectrum in the time domain in the first stage. In the next stage, a fo adaptive procedure using moving averaging in the frequency domain removes the interference in the frequency domain. Finally, we discuss applications of these algorithms to speech processing. |
