3. Setup the Config file.
Go into the cfg folder, open a config file (e.g,*TIMIT_MLP.cfg*,*TIMIT_GRU.cfg*) and modify it according to your paths:
-*tr_fea_scp* contains the list of features created with create_chunks.sh.
-*tr_fea_opts* allows users to easily add normalizations, derivatives and other types of feature processing.
-*tr_lab_folder* is the kaldi folder containing the alignments (labels).
-*tr_lab_opts* allows users to derive context-dependent phone targets (when set to *ali-to-pdf*) or monophone targets (when set to *ali-to-phones --per-frame*).

Please, modify the paths for dev and test data as well.

Feel free to modify the DNN architecture and the other optimization parameters according to your needs.

Note that run_exp performs a full ASR experiment (training, forward and decoding).
If everything is working fine, you should find the following files in in the output folder:
-a file *res.res* summarizing the training and eval performance over the various epochs.
- a file *res.res* summarizing the training and eval performance over the various epochs.
For the MFCC experiment you should obtain something like this:
For the GRU experiment you should obtain something like this:

-a folder *decode_test* containing the speech recognition results. If you type *./RESULTS* you should be able to see the Phone Error Rate (PER%) for each experiment. For instance:
