摘　　要：为能够更准确辨别语音信号特征,通过耦合双谱运算法,结合模块化设计思想,利用Labview进行编程。运算过程中由于复数三阶累积量定义不同使得耦合信息成分不同,因此采取对角切片及双谱分析形式。通过双谱分析能够区分实数域内难以辨别的语音信号,由于上述条件限制,双谱运算结果及对角切片结果存在一定差异。In order to be able to more accurately distinguish the characteristics of the speech signal,through the coupled bispectrum algorithm,combined with modular design ideas,using Labview for programming.In the calculation process,because of the different definitions of complex thirdorder cumulants,the coupling information components are different,so diagonal slice and bispectrum analysis are adopted.Bispectrum analysis can distinguish speech signals that are difficult to discern in the real number domain.Due to the above conditions,the results of bispectrum calculations and diagonal slices are different.
