What is AV-HuBERT?
AV-HuBERT (Audio-Visual Hidden Unit BERT) is an advanced self-supervised learning framework designed for audio-visual speech recognition. It uniquely combines both audio and visual information from speech, analyzing not just the sound but also the speaker's lip movements to improve speech recognition accuracy.
Implementation Details
The model implements a sophisticated multimodal approach to speech recognition by masking multi-stream video input and predicting automatically discovered and iteratively refined multimodal hidden units. The architecture leverages both visual lip-reading capabilities and traditional audio processing to create a robust speech recognition system.
