This paper proposes an enhancement and evaluates the performance of the joint position and pitch estimation (PoPi) algorithm for speaker localization. A modification in the algorithm is introduced in order to improve the performance under high reverberation levels. The performance of the proposed method is evaluated by measuring the correct estimate of(More)
This paper proposes an enhancement and evaluates the performance of a recently proposed method for joint extraction of pitch and direction of arrival for speaker localization. We propose a new weighting function in order to suppress the cross-terms of the aforementioned method. The performance of the method is evaluated by measuring the correct estimate of(More)
In this work a method to track the azimuth (horizontal angle) from multiple speakers in a typically reverberant real office environment is presented. The steered-response-power algorithm (SRP-PHAT) or the recently published joint position and pitch extraction approach (PoPi) combined with a sequential Monte Carlo estimation leads to a robust and fast(More)
