New research explores audio-visual and flow-matching techniques for speech enhancement

Two new research papers explore advanced techniques for speech enhancement using generative models. The first paper introduces Audio-visual Contrastive Alignment (AVCA) to improve diffusion-based speech enhancement by enforcing stronger audio-visual correlation, showing gains in interference suppression and signal reconstruction, particularly at low signal-to-noise ratios. The second paper proposes a novel skip-free backbone for flow-matching speech enhancement, guided by Latent Representation Alignment (LRA) with a Descript Audio Codec, which aims to preserve clean speech representations and enable efficient few-step inference.

    Audio-visual Contrastive Alignment for Diffusion-based Visual-conditioned Speech Enhancement

    arXiv:2606.23712v1 Announce Type: cross Abstract: Audio-visual speech enhancement (AVSE) exploits visual cues such as lip movements to recover speech in noisy environments. Recent work introduced diffusion-based unsupervised AVSE, where a speech diffusion model conditioned on vis…
