In this paper we present an accelerated algorithm for clustering source-dominated microphones in acoustic sensor networks. Predicated on privacy-preserving unsupervised …
In this paper, we propose a robust multi-speaker voice activity detection approach for wireless acoustic sensor networks (WASN). Each node of the WASN receives a mixture of …
Speech enhancement constitutes a great challenge in unknown noisy environments. Many studies have addressed this problem for both single-channel and centralized multichannel …
Detecting the components common or correlated across multiple data sets is challenging due to a large number of possible correlation structures among the components. Even more …
We propose a robust technique for multi-speaker voice activity detection and source enumeration in wireless acoustic sensor networks (WASN). The proposed technique first …
