  • Abstract
    A new set of LP-derived features is introduced. The concept of these features is motivated by the power sum formulation of the LP cepstrum. Due to the fact that the LP model implies that the resulting poles are either real or occur in complex conjugate pairs, the power sum of the poles is equivalent to the power sum of their real components. Therefore, the LP cepstrum is associated to the power sum of the real component of the LP poles. This fact is utilized in deriving a new set of features that is associated to the imaginary components of the LP poles. The author refers to this new set of features as the sepstral coefficients. It is found that the sepstral coefficients and cepstral coefficients are relatively uncorrelated. Hence, they can be used jointly to improve the performance of pattern classification applications where cepstral features are usually used. The author presents some preliminary results on speaker identification experiments
