Design and Implementation of Embedded Speech Recognition System
Wei Wang · Modern Electronics Technique · 2010
The design and implementation of FPGA-based embedded speech recognition system are introduced,the system uses Linear Prediction Cepstral Coefficients(LPCC) algorithm and Dynamic Time Warping(DTW) algorithm,the key components of the system use current popular Virtex-II Pro Series FPGA chip,and use the industry-leading embedded design kit Xilinx ISE Design Suite 10.1,apply modern electronic systems′ hardware and software co-design and co-verification to complete the design.Experiments show that for a small vocabulary and a specific recognition system,it has very good recognition results,recognition accuracy rate is above 95.2%.Recognition performance of this system can meet the basic needs of embedded devices,it has broad application value.
