Re: [Kaldi-users] LibriSpeech DNN forced alignments

Thanks for the prompt reply.

When using steps/online/nnet2/align.sh, I get the following error: "no such
file exp/nnet2_online/nnet_a/conf/online_nnet2_decoding.conf". Do I need to
generate "online_nnet2_decoding.conf" and the "conf" directory with another
script, since they aren't included in the Kaldi-ASR build?
