Implementation and optimization of speaker recognition algorithm based on SOPC

Abstract

Making use of the flexible programmability of SOPC(System On a Programmable Chip) and strong parallel processing ability of FPGA(Field Programmable Gate Array),the speaker recognition algorithm was implemented on FPGA,and the system was optimized in terms of identification speed and accuracy.The principle of speaker recognition algorithm got researched,and according to the characteristics,the SOPC was constructed.It used ping-pong operation to implement voice collection and processing,and used the hardware of FPGA to deal with some time-consuming modules in algorithm so as to quicken the recognition.It also used Genetic Algorithm(GA) to generate template codebook to improve the identification accuracy.Finally,the system realized the function of identity recognition with high real-time quality and accuracy.
