DSP Journal (Special Issue on the Nist Speaker Recognition Workshop) 1999 This article presents the text-independent speaker detection and tracking systems developed by the members of the {ELISA} Consortium for the {NIST'99} speaker recognition evaluation campaign. {ELISA} is a consortium grouping researchers of several laboratories sharing software modules, resources and experimental protocols. Each system is briefly described, and comparative results on the {NIST'99} evaluation tasks are discussed
