- W2368661496 abstract "This paper presents a method to realize formants extraction from speech signal.The weighted Mel-cepstrum coefficients(WMCC),which contain main components of spectrum,are obtained from speech signal by using weighted Mel-cepstrum analysis.The discrete cosine transform(DCT)based smooth algorithm is then applied to the WMCCs to obtain the smooth contour of spectrum in which the peaks of contour are candidate formants.The formant frequencies are selected from candidate formants according to the continuity constrain and the frequency range of formants.Tests show that the errors of this method outperform the cepstrum based method.The method is also robust on noisy speech signal." @default.
