Abstract: Principle and implementation for multichannel real-time speech coder method based on DSP and PC are discussed. In this method, DSP acts as a high efficient speech coder . PC is the controller of full process and decoder. This construction combines the high speed of DSP and the flexibility of PC. The system can meet requirements of speech communication on PSTN, so it has a variety of applications, especially in the industry control.
