Introduction

The 1998 HUB5 English Evaluation, Linguistic Data Consortium (LDC) catalog number LDC2002S10 and ISBN 1-58563-226-0, 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.

Data

This publication contains 40 sphere files encoded in two channel interleaved mulaw for a total of 635,416,388 bytes (605 Mbytes) of sphere data. The sphere headers have been modified from the original Evaluation data by the addition of sample checksums to the 20 CALLHOME data files.

An included documentation table contains information on the speech segments to be processed as follows:
