The NIST Meeting Room Pilot Corpus consists of meeting data collected starting in 2005. The pilot corpus includes meetings of various forms and consists of data recorded simultaneously from multiple microphones and video cameras.

The Pilot Corpus was collected using a specially-constructed realtime multi-media data collection facility. A variety of meeting forums and scenarios were employed to elicit a variety of meeting interaction types and vocabularies. In addition to digital multi-media recordings, the corpus includes a set of ancillary meeting information.
