The purpose of this paper, which deals with research on the linear predictive speech analysis and synthesis system, is to provide feature analysis for the study on speaker recognition and the development of VCEA (Voice Countermeasures Effectiveness Analysis). The analysis conditions and algorithms are determined, an efficient method for pitch extraction is designed, and the TMS32020 software is developed and debugged with the help of computer simulation. Analysis and synthesis are implemented in real time by TMS32020. A single Texas Instruments TMS32020 microprocessor performs LPC analysis, pitch detection, synthesis, and data I/O. >
