# RM setup has weird optimal scaling (ACWT is 1/3) # # This is much larger than 1/10 on SWBD, we use pseudo LM, # so LM scores are likely to be overboosted. # For the discriminative training we will still use acwt 0.1, # scaling down the LM scores did not bring significant improvement. # acwt=0.1 # Large acwt, beams need to be larger too: beam=30.0 # beam for decoding. Was 13.0 in the scripts. latbeam=18.0 # this has most effect on size of the lattices. # We search for optimal WER in low LMWTs: scoring_opts="--min-lmwt 2 --max-lmwt 10" # search acoustic scale in larger values
