The 1997 HUB4 English Evaluation, Linguistic Data Consortium
(LDC) catalog number LDC2002S11 and ISBN 1-58563-227-9, 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.
The purpose of this evaluation is to foster research on the problem of accurately transcribing
broadcast news speech and to measure objectively the state of the art.
Additional documentation is available at the 1997 NIST Evaluation Plan
for Broadcast News webpage.
This year the entire test set is contained in a single waveform
file. The SPHERE-formatted waveforem file h4e_97.sph is located
in the h4e_evl directory of this CD-ROM. The waveform file contains
334 Mbytes of sphere data, which represents
approximately three hours of concatenated radio and television
broadcast news stories. The transcript file contains a rough number of
30,600 total tokens and 4,800 unique tokens.
There are no updates at this time.
