Description:*Introduction* 2001 HUB5 Mandarin Evaluation 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 evaluation was held from February 21 - March 12, 2001. The systems were to produce character-level transcripts and character-level confidence scores for the complete set of evaluation test material. Additional information about the evaluation is available from this NIST website. *Data* The test data comes from unexposed Mandarin CALLHOME Conversations, stored in sphere format. There are 20 sphere files encoded in two-channel interleaved mulaw for a total of 441,990,656 bytes (421 Mbytes) or eight hours of sphere data. These conversations were transcribed and time-marked by speaker turn, by the LDC. An included documentation table contains information on the speech segments to be processed as follows: ... *Updates* There are no updates at this time.
