Deep neural network (DNN)-based speech enhancement algorithms in microphone arrays have now proven to be efficient solutions to speech understanding and speech recognition in noisy environments. However, in the context of ad-hoc microphone arrays, many challenges remain and raise the need for distributed processing. In this paper, we propose to extend a previously introduced distributed DNN-based time-frequency mask estimation scheme that can efficiently use spatial information in form of so… 
Attention-based distributed speech enhancement for unconstrained microphone arrays with varying number of nodes
This paper uses an attention mechanism in order to put more weight on the relevant signals sent throughout the array and to neglect the redundant or empty channels, which can efficiently process the spatial information captured by the different devices of the microphone array.

DNN-based Distributed Multichannel Mask Estimation for Speech Enhancement in Microphone Arrays
