| 摘 要： | 心音信号是一种典型的非平稳信号，传统信号处理方法的应用受到很大限制，为此该文提出了基于Teager边界谱和矢量量化的心音身份确认算法。实验表明，该算法取得很好的识别效果，正确识别率达到96．6％，等错误率仅为5．1％。

| Abstract: | Heart sound signal is a typical nonstationary signals , the application of conventional signal processing method was largely restricted, so the paper proposed a heart sound identification algorithm based on Teager marginal spectrum and vector quantization（VQ）. The experiment results good recognation results, the correct recognition rateis 96.6%, while the equal error rate is algorithm obtains 5.1%. |

| Keywords: | heart sound identification marginal spectrum pattern match |
