Install pipenv using pip install pipenv. Then run

pipenv install

in the source folder to install all python requirements. Alternatively you can use pip install -r requirements.txt to install the requirements using pip instead of pipenv.

Each Oracle method comes with its a command line argument parser. To run one of the method just numerically

python METHOD_NAME.py --eval_dir ./Evaluation_Dir --audio_dir ./Audio_Dir

you can omit either --eval_dir or audio_dir (or both) to not write out the audio_files to disk or do not do the evaluation.
