In this paper, we propose a novel method for tracking two talkers. The tracking is performed using a microphone array and is based on algorithms implemented successively, namely, the PAST (Projection Approximation Subspace Tracking) and IPLS (Interior Point Least Square) algorithms. When multiple sound sources exist, the order of eigenvectors estimated by(More)
In this paper, we propose a novel method for tracking two speakers using a microphone array based on successive algorithms: the PAST and IPLS algorithm. In a situation for which many sound sources exist simultaneously, the order of eigenvectors estimated by the PAST might be replaced in different time-frequency domains. It prevents separation and(More)
