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. </p><p>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. </p><p>Additional documentation is available at the 1997 NIST Evaluation Plan for Broadcast News <a href="http://www.nist.gov/speech/tests/bnr/hub4e_97/hub4e_97.htm" rel="nofollow">webpage</a>. </p><h3>Data</h3> <p>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.
