vsooda / mxnet_kaldi

use mxnet and kaldi to train asr model

note

This is the speech demo from mxnet, but for some reason, they removed this demo. I had contributed timit recipe for this demo, and make it work quite well.

I will update this demo for the latest kaldi and mxnet. currently, we use a old kaldi. we will upgraded to latest in a few day.

thanks for the original author @pluskid and @yzhang87.
