Finetune SSL models for MOS prediction

Overview

Finetune SSL models for MOS prediction

This is code for our paper under review for ICASSP 2022:

"Generalization Ability of MOS Prediction Networks" Erica Cooper, Wen-Chin Huang, Tomoki Toda, Junichi Yamagishi https://arxiv.org/abs/2110.02635

Please cite this preprint if you use this code.

Dependencies:

  • Fairseq toolkit: https://github.com/pytorch/fairseq Make sure you can import fairseq in Python.
  • torch, numpy, scipy, torchaudio
  • I have exported my conda environment for this project to environment.yml
  • You also need to download a pretrained wav2vec2 model checkpoint. These can be obtained here: https://github.com/pytorch/fairseq/tree/main/examples/wav2vec Please choose wav2vec_small.pt, w2v_large_lv_fsh_swbd_cv.pt, or xlsr_53_56k.pt.
  • You also need to have a MOS dataset. Datasets for the MOS prediction challenge will be released once the challenge starts. TODO update with a link.

How to use

  • Modify the paths in mos_fairseq.py to point to your own data and SSL checkpoints.
  • Run python mos_fairseq.py to finetune an SSL model on the data.
  • Modify variables in predict.py to point to your favorite checkpoint.
  • run predict.py to run inference using that checkpoint.
