mHuBERT-147 is a compact yet high-performance multilingual speech recognition model designed to process 147 languages using 90,000 hours of open-licensed audio data. Unlike traditional HuBERT models, it employs discrete speech units optimized through Faiss indexing, enhancing both efficiency and accuracy. The model excels in tasks such as automatic speech recognition (ASR), speech-to-speech translation (ST), and text-to-speech synthesis (TTS), while achieving state-of-the-art results on benchmarks like ML-SUPERB. Its use cases include multilingual transcription, linguistic analysis, and voice assistance in multicultural settings. What sets it apart is its ability to handle a wide range of languages with a lightweight architecture, while incorporating adaptive learning mechanisms for improved generalization.
Documentation
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.

Training
-
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.
ML-SUPERB Scores
mHubert-147 reaches second and first position in the 10min and 1h leaderboards respectively. We achieve new SOTA scores for three LID tasks. See more information in our paper.
