| 摘 要： | 给出了一种串音检测的方案．该方案提出了异常指数的概念，它反映了浊音的非周期性，非周期性的获得利用了并联处理法提取基音频率的技术．实验表明，根据异常指数可准确检测出各种强度的串音，并且异常指数可以在一定程度上反映信噪比的大小．

| Abstract: | This paper is concerned with an approach to the detection of crosstalk, The abnormal index is defined to represent the non-periodicity of the voiced sound. PPROC, which can pick up the frequency of the fundamental frequency, is used to obtain the abnormal index. Experimental results show that the abnormal index can be used to accurately detect the crosstalk of different intensities. In addition, the SNR can be shown by the abnormal index to a certain extent. |
