提出了一种基于同伦理论的语言信号非线性模型分析理论与算法，具有计算量小、稳定性强、收敛性好等一般非线性模型分析方法所没有的优点，同时保持了线性模型的简单性与通用性．实验结果证实了该方法的有效性
A theory and algorithm of nonlinear model analysis of speech signals based on homotopy theory is proposed. It has the advantages of less computational complexity, better stability and better convergence than the general non-linear model analysis methods, while keeping the linear model simple Sex and versatility. Experimental results confirm the effectiveness of this method
