ABSTRACT:
Disclosed is a method of automated speaker identification, comprising receiving a sample speech input signal from a sample handset; deriving a cepstral covariance sample matrix from the first sample speech signal; calculating, with a distance metric, all distances between the sample matrix and one or more cepstral covariance signature matrices; determining if the smallest of the distances is below a predetermined threshold value; and wherein the distance metric is selected fromd5⁡(S,Σ)=A+1H-2,d6⁡(S,Σ)=(A+1H)⁢(G+1G)-4,d7⁡(S,Σ)=A2⁢⁢H⁢(G+1G)-1,d8⁡(S,Σ)=(A+1H)(G+1G)-1,d9⁡(S,Σ)=AG+GH-2,fusion derivatives thereof, and fusion derivatives thereof with⁢d1⁡(S,Σ)=AH-1.
