# MauBERT-phone

MauBERT-phone is a speech model adapting a pre-trained HuBERT base model to predict phones on a subset of 788 hours and
55 languages of Common Voice 16.1 leveraging the phone annotations from VoxCommunis. It was introduced by
the [MauBERT paper](https://aclanthology.org/2026.acl-long.24/) at ACL 2026.

You can load it with [`maubert`](https://github.com/bootphon/maubert):

```python
from maubert import MauBERTPhone

model = MauBERTPhone.from_pretrained("coml/maubert-phone")
```

Check out the [`maubert`](https://github.com/bootphon/maubert) repository if you are interested in further retraining
or fine-tuning, and the [corresponding paper](https://aclanthology.org/2026.acl-long.24/) for our results.

## Files:

- `model.safetensors` and `config.json`: HuggingFace Transformers checkpoint and config.

The manifests, phone alignments, language table and phone inventories used to train this model are released separately
in [`coml/vox-communis-artifacts`](https://huggingface.co/datasets/coml/vox-communis-artifacts). The inventories are
required to reduce the phone head when extracting features from the phone projection layer:

```python
from huggingface_hub import snapshot_download

data_dir = snapshot_download("coml/vox-communis-artifacts", repo_type="dataset")
# then pass f"{data_dir}/canonical_inventories.jsonl" as `inventory_file`
```
