The 2002 NIST Speaker Recognition Evaluation corpus was produced by Linguistic Data Consortium (LDC) catalog number LDC2004S04 and ISBN 1-58563-293-7.
The 2002 NIST Speaker Recognition Evaluation is part of an ongoing series
of yearly 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 text independent speaker recognition. To this
end the evaluation was designed to be simple, to focus on core technology
issues, to be fully supported, and to be accessible.
The 2002 NIST Speaker Recognition Evaluation main data was extracted from the Switchboard Cellular Part 2. The extended data task used two phases of Switchboard II, Phases 2 and 3. This evaluation also included the first multi-modal task, using data from the FBI voice database.
Supporting documentation for this evaluation may be found on the 2002 NIST Speaker Recognition Evaluation
website. Please consult the NIST evaluation plan for detailed instructions on using this evaluation material.
There are a total of 9,153 speech
files (6,098 at 8 KHz and 3,055 at 16KHz), all of which are in sphere format, for a total of ~156 hours.
The data was initially distributed by NIST on 13 CD-ROMs (r81_1_1 through r81_13_1). This corpus consists of training and test data and replicates exactly the content and structure of the 13 CD-ROMs.
There are no available updates at this time.
