To locate the position of the speaker, there are many methods, among of them, the method using steered response power is very popular. By phase transform, the steered response method (SRP-PHAT) is robust; with the noise increasing, the performance of the method becomes bad. Using principal eigenvector, the steered response power (SRP-PE) method is better than SRP-PHAT. In this paper, we propose an...
Methods based on pattern recognition such as support vector machine or neural network, can overcome the deficiency of traditional sound source localization algorithms which have an insufficient robust ability in the harsh environment of small SNR and severe reverberation. Among those methods, Naive-Bayes classifier has a high accuracy to locate sound source with a small amount of calculation and strong...
Sound source localization plays a crucial role in many microphone arrays application, ranging from speech enhancement to human–computer interface in a reverberant noisy environment. The steered response power (SRP) using the phase transform (SRP-PHAT) method is one of the most popular modern localization algorithms. The SRP-based source localizers have been proved robust, however, the methods may...

Sound source localization is essential in many microphone arrays application, ranging from teleconferencing systems to artificial perception in a reverberant noisy environment. The steered response power (SRP) using the phase transform (SRP-PHAT) source localization algorithm has been proved robust, however, the performance of the SRP-PHAT algorithm degrades in highly reverberant noisy environment...
Speech source location estimation in a noisy, reverberant environment has attracted much attention recently. It was found that the localization method through calculating the steered response power (SRP) is more robust than time-difference-of-arrival (TDOA)-based localization method. The method places equal emphasis on each microphone pair in calculation of the SRP. In a room, each microphone is usually...
