Abstract [en]

Development of a low bit-rate voice over IP application is described. A speech coding algorithm is constructed and implemented on a digital signal processor (DSP). The algorithm is based on a sub-band mixed excitation LPC vocoder structure and operates at a rate of 2000 bits per second. Implementation is done on two TMS320C6701 floating point DSP’s each connected to a PC. On the PC, a graphical user interface (GUI) controls the data flow over the IP network. The application runs in full duplex and supports poor to fair sound quality depending on the used recording equipment.
