This publication contains the speech data and transcripts used as the EvalSet data in NIST's 1997 Hub5 English Evaluation. The DevSet data for this evaluation consists of the EvalSet data from the CALLHOME American English Speech corpus.
The 1997 Hub5 English evaluation was 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.
More information is available at NIST's web site for The 1997 Hub-5E Spring Evaluation.
This publication contains 40 audio sphere files, each with a corresponding transcript. The sphere headers have been modified from the original evaluation data by the addition of sample checksums to the CALLHOME data files.
