[Kaldi-users] Help in understanding score_combine

[karthick <cre...@gm...>]

Hi Friends,

Recently I noted that when I used local/score_combine.sh from TIMIT task to
combine the lattices of the same dnn model it gave reduced error rate.

The actual DNN performance was 18.4 % PER, the combination of the same
model gave a % PER of 16.9. Since, I am new to this lattice_combination
approach can someone suggest me how it works ? and whether the result what
i got is correct ?
