The 2004 NIST Speaker Recognition evaluation is part of an ongoing series of yearly evaluations conducted by NIST (National Institute of Standards and Technology). These evaluations provide an important contribution to the direction of research efforts and the calibration of technical capabilities. They are intended to be of interest to all researchers working on the general problem of text-independent speaker recognition. To this end the evaluation was designed to be simple, to focus on core technology issues, to be fully supported, and to be accessible.
NIST has been coordinating Speaker Recognition Evaluations since 1996. Each evaluation begins with the announcement of the official evaluation plan which clearly states the rules and tasks involved with the evaluation. The evaluation culminates with a follow-up workshop, where NIST reports the official results and researchers share in their findings.
The data consists of conversational telephone speech collected by the LDC.
