摘要：This paper describes a neural network speech enhancement system using Multilayer Perceptron(MLP) network and trained using the back propagation algorithm (BPA). Speech enhancement isgenerally refers to map noisy speech into cleaner speech. Noisy speech signals are obtained byadding random noise to the clean signals .Speech enhancement is then performed on the noisysignals by using the ADALINE. Here we show that neural nets can be used to significantly boostrecognition accuracy, without retraining the speech recognizer
