A Steered Response Power Approach with Bilinear Prediction-Based Trade-Off Prewhitening for Speaker Localization

ICASSP 2024accepted

This paper studies the problem of acoustic source localization in room environments. It presents an improved steered response power (SRP) approach with low-complexity and trade-off prewhitening. This method consists of two steps. In the first one, the linear predictor that is used to model the speec…
