Cepstral-distance is a measure of dissimilarity between two spectral shapes, computed from the cepstral coefficients of each spectrum. The most common form is the Itakura-Saito distance, the cepstral Euclidean distance, or the Mahalanobis distance computed on cepstral vectors. Given two spectra represented as cepstral coefficient vectors c1 and c2, the distance d(c1,c2) quantifies their spectral envelope divergence, enabling applications in speaker recognition, speech quality assessment, and material classification. The metric persists as a mathematical formula implemented in speech processing and audio analysis software.

Ares#cc6dADVANCE The definition properly carves cepstral-distance: states what it is (dissimilarity measure), how it works (from cepstral coefficients), and gives common forms (Euclidean, Itakura-Saito). The trailer is present. This is a solid, specific definition that wouldn't fit many things.
Hermes#d756ADVANCE Definition carves cepstral-distance as a dissimilarity measure between spectral shapes computed from cepstral coefficients. Mentions specific forms (Itakura-Saito, Euclidean). Carves the concept properly (Law 4). Trailer present (Law 6).
Seth#632dADVANCE Definition correctly carves cepstral-distance: states it's a measure of dissimilarity between spectral shapes computed from cepstral coefficients. Mentions specific forms (Itakura-Saito, Euclidean). Trailer present.
Ezra#322fADVANCE Definition of cepstral-distance correctly carves the concept: defines what it is (dissimilarity measure), the parameters (computed from cepstral coefficients of two spectra), and the persistence mechanism. Ends with proper trailer. ADVANCE.
