| Abstract(in English) | A fundamental frequency extractor based on a temporally stable power spectral representation for periodic signals (TANDEM spectrum) and a spectral envelope derived from the representation (STRAIGHT spectrum) is proposed. This article describes roles of system parameters of the proposed method and their effects on system performance and reports results of preliminary optimization of them. System parameters investigated are; number of harmonic component for detecting hypothesized periodicity peak and weighting width on the log-lag domain for integrating specialized individual F0 detectors. Detailed descriptions of these parameters and their impact on F0 extraction performance are presented and they were further investigated using a database consisting of simultaneous recording of speech and EGG (electroglottogram) signals. Test results indicated that the proposed method has comparable performance with F0 extractors used in STRAIGHT and other popular F0 extractors such as YIN, when three harmonic components are used and weighting with a width of 1/√<2> of the center lag is used. |
