AB  - The Steered Response Power - Phase Transform (SRP-PHAT) algorithm has been shown to be one of the most robust sound source localization approaches operating in noisy and reverberant environments. A recently proposed modified SRP-PHAT algorithm has been shown to provide robust localization performance in indoor environments without the need for having a very fine spatial grid, thus reducing the computational cost required in a practical implementation. Sound source localization methods are commonly employed in many sound processing applications. In our case, we use the modified SRP-PHAT functional for improving noisy speech signals. The estimated position of the speaker is used to calculate the time-delay for each microphone and then the speech is enhanced by aligning correctly the microphone signals.
