The Lincoln Speaker Recognition System: NIST Eval2000

This paper presents an overview of the Lincoln Laboratory systems fielded for the 20006 NIST speaker recognition evaluation (SREOO). In addition to the standard one-speaker detection tasks, this year's evaluation, as in 1999, included multi-speaker spokes dealing with detection, tracking and segmentation. The design approach for the Lincoln system in SREOO was to develop a set of core one-speaker detection and multi-speaker clustering tools that could be applied to all the tasks. This paper will describe these core systems, how they are applied to the SREO0 tasks and the results they produce. Additionally, a new channel normalization technique known as handset-dependent test-score norm (HTnorm) is introduced.
