Recently, proposed recurrent neural network (RNN) based all deep learningminimum variance distortionless response (ADL-MVDR) beamformer method yielded superior performance over the conventional MVDR by replacing the matrixinversion and eigenvalue decomposition with two RNNs . Temporal-spatial self-attention module is proposed to better learn thebeamforming weights from the speech and noise spatial spatial spatial covariance matrices . Thetemporal self-association module could help RNN to learn global statistics ofcovariance matrics . The spatial self-appearance module is designed to attend on the cross-channel correlation in the covariance matrix matrices. Furthermore, amulti-channel input with multi-speaker directional features and multi
