| 摘 要： | 为对构音异常声道实行辅助治疗,使用Matlab对声道进行动态仿真.采用极点形式在牛顿插值的基础上进行迭代计算出共振峰,对声道进行非线性分段,使用Matlab实现分段后声道形状显示;使用参数Corana改进算法,优化9个声道参数.在进行大量迭代计算获得合适的声道参数后,显示优化后的声道形状.该形状可以为构音治疗师的治疗提供参考.使用声门激励模型产生用于激励的声音,能够合成用于反馈的声音.实验证明该声道仿真模型可以为治疗提供参考.

| Abstract: | To implement the auxiliary treatment of dysarthria,Matlab is used to fulfill the dynamic simulation of vocal tract. By the pole's form,the iterative calculation is used to get the formant on the basis of Newton interpolation. The non-linear subsection is done on vocal tract and Matlab is used to implement the vocal tract shape display after subsection. The Corana parameter is used to improve the calculation to optimize nine vocal tract parameters. A large number of iterative calculation is accomplished to o... |
