# CHiME-4 1ch track results
# The result is based on Hori et al, "The MERL/SRI system for the 3rd CHiME challenge using beamforming,
# robust feature extraction, and advanced speech recognition," in Proc. ASRU'15,
# and please refer the paper if you think the baseline useful.
# Note that the following result is different from that in the paper since we don't include
# SRI's robust features and system combination
