Research questionHow can causal spatial filters track moving speakers when only their initial directions are known?A spatial filter tuned to a speaker’s starting direction can lose the target as the speaker moves. Frame-wise causal processing also limits the information available for updating the direction estimate.

Latest papersRecent research connected to this question, newest first.Autoregressive Guidance of Deep Spatially Selective Filters using Bayesian Tracking for Efficient Extraction of Moving SpeakersThe work studies Bayesian tracking that uses enhanced speech to autoregressively guide arbitrary deep spatial filters. Evidence comes from synthetic trajectories generated with a social force model and real-world recordings, including unseen acoustic conditions.research paper · Sep 8, 2026
