A speaker verification system receives input speech from a speaker of unknown identity. The speech (12, 14) undergoes LPC analysis and transformation to maximize separability between true speakers and impostors when compared (16) to reference speech parameters which have been similarly transformed. The transformation incorporated a "inter-class" covariance matrix of successful impostors within a database.
