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 at ACL 2026.

You can load it with maubert:

from maubert import MauBERTPhone

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

Check out the maubert repository if you are interested in further retraining or fine-tuning, and the corresponding paper 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. The inventories are required to reduce the phone head when extracting features from the phone projection layer:

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`
