| Abstract(in English) | In this paper, we describe about valley-cepstral coefficients which are obtained from the part of valley of spectral envelope and Δ-coefficients and ΔΔ-coefficients which are dynamic features and are obtained from the products of cepstral coefficient and its absolute value. We can easily extract the part of the valley from the spectral envelope by nonlinear processing. We can also easily obtain the censtral coefficients from the part of valley. we show the effectiveness of these coefficients in the experiments of the phonemerecognition using the feature vector by transform based on discriminat analysis of the raw feature vector whose components are these coefficients and the segment of LPC coefficients. |
