For the conference room environment the submission consisted on one primary system in each of the MDM and SDM conditions. The MDM system uses filter&sum to acoustically fuse all the available channels into one enhanced channel. Then it applies the speaker diarization to this enhanced channel. The SDM condition skips the filter&sum processing, as the system's input is already a single channel (from the most centrally located microphone according to NIST). The filter&sum processing lacks some of the delay post-processing improvements presented in RT06s.
