The NIST meeting room corpus 2 phase 1

The Speech Group and Smart Spaces Lab of National Institute of Standards and Technology's Information Technology Laboratory have collaborated to collect a second phase of meetings in the NIST Meeting Data Collection Laboratory. The meeting laboratory, which was used to collect a 15 hour pilot corpus beginning in 2001, was updated with 7 HDV cameras and new head microphones for participants to collect a twenty hour corpus to support ARDA's Video Analysis and Content Exploitation (VACE) program. For the second phase of data collection, a strong emphasis was placed on high resolution video along with video calibration to enable various visual processing applications such as three dimensional person tracking. This paper documents the evolution of the meeting room to its current form and describes the key components of the phase II corpus.
