Auxiliary Function-Based Algorithm for Blind Extraction of a Moving Speaker
Original language description
We propose a novel algorithm for Blind Source Extraction (BSE) of a moving acoustic source recorded by multiple microphones. The algorithm is based on Independent Vector Extraction (IVE) where the contrast function is optimized using the auxiliary function-based technique. The recently proposed Constant Separating Vector (CSV) mixing model is assumed, which allows for movements of the extracted source within the analyzed batch of recordings. We provide a practical explanation of how the CSV model works when extracting a moving acoustic source. Then, the proposed algorithm is experimentally verified on the task of blind extraction of a moving speaker. The algorithm is compared with state-of-the-art blind methods and with an adaptive BSE algorithm which processes data in a sequential manner. The results confirm that the proposed algorithm can extract the moving speaker better than the BSE methods based on the conventional mixing model and that it achieves improved extraction accuracy than the adaptive method.
