VM-ARRAYDPS: Virtual Microphone Augmented Diffusion Posterior Sampling for Unsupervised Blind Speech Separation

Blind Source Separation(BSS) is a fundamental problem in signal processing, aiming to separate multiple source signals from their mixtures without prior knowledge of the sources or the mixing process. Traditional approaches, such as Independent Vector Analysis (IVA) exploits statistical independence of sources. Recentl...

Separate First, Then Associate: A Two-Stage Approach for Real-World Audio-Visual Speech Enhancement

This work proposes a decoupled separation-then-association approach for AVSE, which consists of a separation stage in which a trained, audio-only model is used to separate input multi-speaker mixture to individual speaker signals, followed by an association stage where an audio-visual CLIP model is used to identify the...
