[Kaldi-users] Monophone DNN traning on TIMIT

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

Hi All,

I am trying to train a DNN for TIMIT as it is much smaller to play with.
So, I modified the run_dnn.sh file given in the wsj/s5 setup. However,
while trying to perform sMBR, following error occurred. Your advice is
highly appreciated.

Thanks,
Lahiru
