Topic Detection and Tracking (TDT) 2 Mandarin Audio Corpus contains approximatley 52 hours of recordings of broadcast news audio. The transcriptions to these recordings are available in the Topic Detection and Tracking (TDT) 2 Multilanguage Text Version 4.0, LDC2001T57.

Topic Detection and Tracking (TDT) refers to automatic techniques for finding topically related material in streams of data such as newswire and broadcast news. The TDT2 corpus was created to support three TDT2 tasks: find topically homogeneous sections (segmentation), detect the occurrrence of new events (detection), and track the reoccurrencce of old or new events (tracking).
