摘要：
Speech recognition using self-correlation (auto-correlation) parameters and time normalization is improved by first making a preliminary decision using lower-order (zeroth to third) self-correlation coefficients derived from the self-correlation function of order m: ##EQU1## where .phi.(0) is the power, .phi.(1) is the linear or first order coefficient, and so on.
