“…Dealing with the magnitude of the autocorrelation sequence, which is our concern in this paper, among the most successful methods, we can name Differentiated Relative Autocorrelation Sequence Spectrum (DRASS) [6], Short-time Modified Coherence (SMC) [7], One-Sided Autocorrelation LPC (OSALPC) [8], Relative Autocorrelation Sequence (RAS) [9], Autocorrelation Mel Frequency Cepstral Coefficients (AMFCC) [10] and Differentiation of Autocorrelation Sequence (DAS) [11]. Also, it has been shown that the use of spectral peaks obtained from a filtered autocorrelation sequence can lead to a good performance under noisy conditions [12,13].…”
