This is code adapted from the baseline model for the VoiceMOS 2022 challenge to be used for convenient MOS prediction on arbitrary audio data.

For the original code please refer to: https://github.com/nii-yamagishilab/mos-finetune-ssl, which is provided by the National Institute of Informatics, Japan.

The audio normalization scripts are taken from: https://zenodo.org/record/6572573
