Neural Network Based Time-Frequency Masking and Steering Vector Estimation for Two-Channel Mvdr Beamforming

We present a neural network based approach to two-channel beamforming. First, single- and cross-channel spectral features are extracted to form a feature map for each utterance. A large neural network that is the concatenation of a convolution neural network (CNN), long short-term memory recurrent n…
