Diffusion-based Unsupervised Audio-visual Speech Enhancement
ICASSP 2025accepted
This paper proposes a new unsupervised audiovisual speech enhancement (AVSE) approach that combines a diffusion-based audio-visual speech generative model with a non-negative matrix factorization (NMF) noise model. First, the diffusion model is pre-trained on clean speech conditioned on correspondin…
