HuBERT MMS-ulab

HuBERT MMS-ulab is a HuBERT base model pretrained on the Segmented MMS ulab v2 dataset for the DiscoPhon benchmark. It was pretrained using the minimal_hubert library.

You can load it with HuggingFace Transformers:

from transformers import HubertModel

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

Or with minimal_hubert:

from minimal_hubert import HuBERT, HuBERTPretrain

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

Check out minimal_hubert if you are interested in pretraining or want to load HuBERT checkpoints from different libraries.

• 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 MMS-ulab. Used to train the 1st iteration.
• km500-it1-l9.joblib: K-means trained on features from the 9th layer of the 1st iteration model. Used to train the 2nd iteration.
• km256-it2-l12.joblib: K-means trained on features from the 12th layer of the 2nd iteration model. Used for DiscoPhon finetuning.
