| 英文摘要 | 动态时间规整(dynAMIC TIME WArPIng,dTW)是一种相对简单成熟的算法,广泛用于语音识别系统中.针对环境噪声对声纹识别系统性能的影响,用信噪比关联谱减及自适应门限端点检测进行抗噪声处理,在此基础上采用dTW算法设计了基于嵌入式ArM9平台的声纹识别实现方案,并给出了带噪环境下的声纹识别实验结果.; 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.; 福建省高校产学合作重大项目(2010H6022);福建省杰出青年科学基金项目(2010D003);厦门市科技计划项目(3502Z20113008) |
