| Abstract(in English) | This paper proposes a spectrum estimation method for speech signals of short pitch period. The spectral envelope obtained from the conventional linear prediction method weights the local maxima more heavily than the local minima. Therefore, when the formants locate at the valleys between harmonics, the formant estimation error increases. The proposed method is one of the approaches to the above-mentioned problem. The proposed method consists of two-stage analyses. The valleys of harmonics are removed by using cepstrum analysis repeatedly in the first stage. Then, the spectral envelope are estimated by using the autocorrelation method in the second stage. This paper shows that the proposed method can estimate the formant frequencies of speech signals uttered by children more accurately than the conventional linear prediction method. |
