Sound event detection and localization (SDL) is helpful for extracting information about the position of sound sources in real time using a microphone array. This paper develops an SDL system for intelligent outdoor security cameras, so that it can listen and react to the surrounding acoustic events. In outdoor environments, this task is challenging due to high-energy and non-stationary noises such...
In realistic environments, mismatches between the calculated angle-TDOA map with its real exact values are the major reason of performance degradation in sound localization. Usually, those mismatches come from some certain configuration errors or deviations caused by the change of environments. To reduce those mismatches, in this paper we proposed an angle-TDOA map adaptation method which can achieve...
In this paper, we present some methods to improve the performance of microphone array speech recognition system based on Limabeam algorithm. For improving recognition accuracy, we proposed weighted Mahalanobis distance (WMD) based on traditional distance measure in a Gaussian classifier and is a modified method to give weights for different features in it according to their distances after the variance...
