Abstract :
The paper discusses the method that uses the BP algorithm of neural networks to code the speech signal by means of nonlinear prediction aiming at the non-stationary and nonlinear features of speech signals. Taking the G.721 ADPCM speech coding algorithm as an example, the method of nonlinear prediction replacing linear prediction is presented. The results indicate that the coding quality using neural network nonlinear prediction is better than that of using linear prediction
