The paper introduces a specific isolated word speech recognition systems based on fixed-point DSP,focusing on achieving the rapid extraction algorithm parameters.The algorithm is based on dynamic programming(DP) technology Dynamic Time Warping algorithm(DTW),by using VAD bipolar endpoint detection programmers to improve the accuracy of endpoint detection,and MFCC for speech recognition parameters.The paper firstly discusses realizing methods of standard floating-point.Then combining with its fixed-point DSP...
