# HuBERT VP-20

HuBERT VP-20 is a HuBERT base model pretrained on a subset of 6k hours and 20 languages of VoxPopuli
(all EU languages except English, French, and German) for the [DiscoPhon benchmark](https://benchmarks.cognitive-ml.fr/discophon).
It was pretrained using the [`minimal_hubert`](https://github.com/mxmpl/minimal_hubert) library.

You can load it with HuggingFace Transformers:

```python
from transformers import HubertModel

model = HubertModel.from_pretrained("coml/hubert-base-vp20")
```

Or with `minimal_hubert`:
```python
from minimal_hubert import HuBERT, HuBERTPretrain

# Standard model
model = HuBERT.from_pretrained("coml/hubert-base-vp20")
# With pretraining head for classification
model_for_pretraining = HuBERTPretrain.from_pretrained("https://huggingface.co/coml/hubert-base-vp20/resolve/main/it2.pt")
```

Check out [`minimal_hubert`](https://github.com/mxmpl/minimal_hubert) if you are interested in pretraining or want
to load HuBERT checkpoints from different libraries.

## Files:

- `model.safetensors` and `config.json`: HuggingFace Transformers checkpoint and config.
- `it1.pt`: 1st iteration checkpoint.
- `it2.pt`: 2nd iteration checkpoint. Converted to HuggingFace state_dict to get `model.safetensors`.
- `km100-mfcc.joblib`: K-means trained on MFCCs of VoxPopuli-20. Used to train the 1st iteration.
- `km500-it1-l10.joblib`: K-means trained on features from the 10th layer of the 1st iteration model. Used to train the 2nd iteration.
- `km256-it2-l11.joblib`: K-means trained on features from the 11th layer of the 2nd iteration model. Used for DiscoPhon finetuning.
