Re: [Kaldi-users] Error of DNN Hybrid Training

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

The error says that, you are calling splice-feats using wrong option values.
The command you used is "splice-feats --left-context=splice_width 
--right-context=splice_width ark:- ark:- |' - "
'splice_width' was not interpreted as an 'integer' value. Check where is 
it defined.
There is a chance that you are not using the correct bash.
