Huggingface Implementation of AV-HuBERT on the MuAViC Dataset

This repository contains a Huggingface implementation of the AV-HuBERT (Audio-Visual Hidden Unit BERT) model, specifically trained and tested on the MuAViC (Multilingual Audio-Visual Corpus) dataset. AV-HuBERT is a self-supervised model designed for audio-visual speech recognition, leveraging both audio and visual modalities to achieve robust performance, especially in noisy environments.

Key features of this repository include:

• Pre-trained Models: Access pre-trained AV-HuBERT models fine-tuned on the MuAViC dataset. The pre-trained model been exported from MuAViC repository.

• Inference scripts: Easily pipelines using Huggingface’s interface.

• Data preprocessing scripts: Including normalize frame rate, extract lips and audio.
