Table 3 Effect of the various choices in the design of the system’s first stage (discussed in Section 4.4) to the room-localized SAD performance on the DIRHA-sim test set

From: Room-localized speech activity detection in multi-microphone smart homes

  1. For consistency, the first stage is always followed by the second stage of the MFCC/GMM baseline of Section 6.1. RI denotes room-independent operation (“oper”) of the first stage and RL room-localized one
