| Abstract: | On the basis of analyzing the feature of the speech signal processing chip, the microcomputer speech system made of AT89C2051 and ISD25120 is designed. Compared with the traditional speech signal processing technology,the system has the advantage of simple circuit, short developing period and Hi-Fi speech. It was proved by consumers that the system could be operated easily, relied on strongly, and with excellent speech. So it can be served as sub-system in computer speech system. |
