This project computes GOP (Goodness of Pronunciation) bases on Kaldi.

1. Download and complile Kaldi. Note that you need to check out the branch 5.1 instead of master, and do not use the "--shared" option.
2. Edit src/CMakeLists.txt to set the variable $KALDI_ROOT.
3. Compile the binary:

cd src/
mkdir build && cd build
cmake .. && make

cd egs/gop-compute
./run.sh

You can find the GOP raw scores in eval_gop/gop.1 and the corresponding phoneme sequence (in numbers) in eval_gop/phonemes.1

1. Download the sample data and extract all files under egs/gop-compute. This package provides a toy speech dataset as well as a pretrained acousitc model
2. Run ./run_tri6b.sh data/sample_raw_data/ for a demo
3. Run ./run_tri6b.sh for usage information
4. If you want to use your own data, you can organize your files similar to data/sample_raw_data/ in the sample data package
5. The code assumes that the name of the root dir of your own data is the same as the speaker's ID, see data/sample_raw_data/spk2gender
6. This script also outputs the symbolic phoneme sequence in eval_gop_tri6b/phonemes_sym.*

Huge thanks to Junbo Zhang for his initial kaldi-gop repository. I added the phoneme output and added an example on how to use another acoustic model for the computation.
