A deep neural networks (DNN) based close talk speech segregation algorithm is introduced. One nearby microphone is used to collect the target speech as close talk indicated, and another microphone is used to get the noise in environments. The time and energy difference between the two microphones signal is used as the segregation cue. A DNN estimator on each frequency channel is used to calculate the parameter masks. The parameter masks represent the target speech energy in each time frequency (T-F) units. Experiment results show the good performance of the proposed system. The signal to noise ratio (SNR) improvement is 8.1 dB on 0 dB noisy environment.
