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
, orxlsr_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.
