A new cepstral function, the cepstrum of the one-sided autocorrelation sequence, is presented and applied to pitch determination of speech signals. It shows a performance in terms of pitch period errors significantly better than those of the usual cepstrum and autocorrelation with center clipping algorithms for both clean and noisy speech, due to its remarkable accuracy at non-stationary segments of speech signals and to its noise reduction capability.
