preliminarily confirmed DNN's sparsity from the weights by Matlab and showed the weights' distribution graphicly;
more systematic knowlege about ASR has been gained;
CONTEXT was not yet studied carefully, :(
discover more things in the weights if it has more;
do some literature analysis about CONTEXT;
go through the OBD-based sparse DNN-HMM.
