| Abstract: | Dynamic time warping(DTW) is a relatively simple and effective algorithm,which is widely used in speech recognition systems.In order to deal with the performance degration caused by background noise,this paper utilized signal to noise ratio(SNR) spectral substration algorithm and adaptive threshold endpoint detection algorithm.Basing on the two algorithms,the speech recognition system is successfully implemented on ARM9 embedded microprocessor.Finally the experimental results are given to verify the effectiveness of the proposed system. |
