1998 HUB5 English Transcripts was developed by the Linguistic Data Consortium and consists of transcripts of 40 English telephone conversations used in the 1998 HUB5 evaluation sponsored by NIST (National Institute of Standards and Technology). 

The Hub5 evaluation series focused on conversational speech over the telephone with the particular task of transcribing conversational speech into text. Its goals were to explore promising new areas in the recognition of conversational speech, to develop advanced technology incorporating those ideas and to measure the performance of new technology. Further information about the evaluation can be found on the NIST HUB5 website.


This release contains transcripts in .txt format for the 40 source speech data files used in the evaluation: (1) 20 telephone conversations from Swtichboard-2 Phase 1 (LDC98S75) in which recruited speakers were connected through a robot operator to carry on casual conversations about a daily topic announced by the robot operator at the start of the call; and (2) 20 telephone conversations from CALLHOME American English Speech which consists of unscripted telephone conversations between native English speakers.

The corresponding speech data is released as 1998 HUB5 English Evaluation (LDC2002S10).
