Quick instruction:
1) download CHiME1 data
Check the download page http://spandh.dcs.shef.ac.uk/projects/chime/PCC/datasets.html
Train set
http://spandh.dcs.shef.ac.uk/projects/chime/PCC/data/PCCdata16kHz_train_reverberated.tar.gz
Devel set
http://spandh.dcs.shef.ac.uk/projects/chime/PCC/data/PCCdata16kHz_devel_isolated.tar.gz
Test set
http://spandh.dcs.shef.ac.uk/projects/chime/PCC/data/PCCdata16kHz_test_isolated.tar.gz
2) move to Kaldi CHiME1 directory, e.g.,
cd kaldi-trunk/egs/chime1/s5
3a) specify Kaldi directory in path.sh,
export KALDI_ROOT="<your kaldi directory>/kaldi-trunk"
3b) specify CHiME1 signal directory and CHiME1 recogniser directory for your
username ($USER) in config.sh.
By default, directories data/ exp/ mfcc/ will be created by the recipe in the
Kaldi CHiME1 recogniser directory. You could link these to directories on a
different disk space or specify a different directory in config.sh,
export WAV_ROOT="<your CHiME1 directory>/PCCdata16kHz"
export REC_ROOT="."
4) execute run.sh
./run.sh
4*) we suggest to use the following command to save the main log file
nohup ./run.sh > run.log
5) You can find result at exp/tri2b/decode_*/keyword_scores.txt
