Introduction

The 2000 HUB5 English Evaluation, Linguistic Data Consortium (LDC) catalog number LDC2002S09 and ISBN 1-58563-225-2, is part of an ongoing series of periodic evaluations conducted by NIST. 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 conversational speech recognition. To this end the evaluation was designed to be simple, to focus on core speech technology issues, to be fully supported, and to be accessible.

Additional documentation is available at the 2000 NIST Evaluation Plan for Recognition of Conversational Speech Over the Telephone website.
