The new feature is termed as warped-discrete cosine transform cepstrum (WDCTC). The feature is obtained by replacing the discrete cosine transform (DCT) by the warped discrete cosine transform (WDCT, 4) in the discrete cosine tranform cepstrum (DCTC 2). The WDCT is implemented as a cascade of the DCT and IIR all-pass filters. We incorporate a nonlinear frequency-scale in DCTC which closely follows the barkscale. This is accomplished by setting the all-pass filter parameter using an expression given by Smith and Abel 5 . Performance ofWDCTC is compared to mel-frequency cepstral coefficients (MFCC) in a speech recognition and speaker identification experiment. WDCTC outperforms MFCC in both noisy and noiseless conditions.
