This repository contains the best mHuBERT-147 pre-trained model.
MODEL DETAILS: 3rd iteration, K=1000, HuBERT base architecture (95M parameters), 147 languages.
mHuBERT-147 models
mHuBERT-147 are compact and competitive multilingual HuBERT models trained on 90K hours of open-license data in 147 languages.
Different from traditional HuBERTs, mHuBERT-147 models are trained using faiss IVF discrete speech units.
Training employs a two-level language, data source up-sampling during training. See more information in our paper.
Manifest list available here. Please note that since training, there were CommonVoice removal requests. This means that some of the listed files are no longer available.
Fairseq fork contains the scripts for training with multilingual batching with two-level up-sampling.
mHubert-147 reaches second and first position in the 10min and 1h leaderboards respectively. We achieve new SOTA scores for three LID tasks.
