Neural Network Based on Microphone Array for Speech Enhancement
Guang Zhao · 2005
Adaptive Linear Neuron (ADALINE) neural network based on microphone array speech enhancement method was described, concerning with noise scattering field in closed environment, which take advantage of characteristics of both beamforming and neural network. An improvement was made upon the structune on basis of MLP-BP, so as to enhance convergent speed of neural network learning method. Simulation results indicate that compared with Multiplier Linear Perception neural network using backpropagation (MLP-BP) algorithm, the proposed method exhibits higher processing speed and better noise suppression performanc
