| Abstract: | This article introduces a type of adaptive FIR filter algorithm for speech enhancement based on linear prediction,which can filter the noisy speech signal in real-time and improve SNR so that the recognition performance of the speech recognition system can be improved. The Emulation result shows that the adaptive filter with linear prediction achieves effective noise suppression. |
