Initial Steps to use Kaldi

Please note that it's better if you used Linux, for me I'm using Ubuntu on Windows (WSL)

1. Download Kaldi using
   git clone https://github.com/kaldi-asr/kaldi.git kaldi-trunk --origin golden
2. Go to kaldi-trunk/tools/extra/ and run the script ./check_dependencies.sh, follow the instructions and re-run it again till it outputs :

./check_dependencies.sh: all OK.  

3. Install Kaldi using by doing the following: In kaldi-trunk/tools/ do :

   make -j 8; cd ../src; ./configure; make -j 8
   

   -j 8 will run 8 jobs in parallel because it may take a while, you can change it to the number of processors you have. use nproc to check how many logical processors your device have
4. Go to kaldi-trunk/tools/ and install SRILM using the script ./install_srilm.sh Note that you may need to go to SRILM website and download the SRILM and put it in the directory kaldi-trunk/tools/ and rename it to srilm.tgz before running the script
5. Go to kaldi-trunk/egs/ and clone this repo using git clone https://github.com/Hamahmi/kaldi-tut.git
6. Source tools/env.sh in path.sh by adding

# Sourcing tools/env.sh ~H
. ../../tools/env.sh

in path.sh

7. Change the paths in the files to be correct instead of home/hamahmi/kaldi-trunk/ use your own path
8. Run the scripts script_for_utt2spk.sh, script_for_wav.scp.sh, and script_for_text.sh in both kaldi-trunk/egs/kaldi-tut/digits_audio/test/ and kaldi-trunk/egs/kaldi-tut/digits_audio/trainto generate the respective files. Completing these steps ensures that the data has been properly set up.
9. Run the script ./run.sh :D
