摘要： 利用LPC求残差系数,然后对残差系统求自相关,再判断自相关的参数序列是否具有周期性而实现清浊音的判决。利用此算法结合计算机的智能诊断实现了一个应用系统,此应用系统能够让语言障碍患者进行清浊音康复训练,在临床应用中取得了良好的效果。

Abstract: In this paper, firstly the coefficient of incomplete margin is calculated with LPC method, then the autocorrelation of the speech and sequentially, the autocorrelation of the speech is judged whether is seasonal. By doing this, people can complete voicing decision. Combined with the computer aptitude diagnoses, an application system is actualized. Language barrier sufferers can do healing training with it. Good effect is gained in clinic application.
