An extensive speech database was collected in two experimental enclosures for research on microphone arrays. The first enclosure is a digitally controlled variable acoustics facility where the reverberation time can be adjusted from 1.7 s to 0.1 s, and the second is a regular hard-walled laboratory. Two different sets of data were collected to address source location and spatial volume selectivity issues. Preliminary results on Matched-filter processing and on Source location are reported for the new database.
