摘要 本文阐述了一种改进的自相关算法原理和HILBERT变换原理[1];提出了运用这些原理以及精确的搜索算法来精确确定语音浊音中最大激励值的位置的方法,同时设计了能自动确定语音最大激励位置的软件.通过对大量的不同种类的语音进行运算和统计,证明了这种算法的可靠性是较高的. The paper introduces an improved auto-correlation method and the princi-ple of HILBERT transform as well as an accurate searching method for determining theinstants of maximum excitations in voiced speech. A computer software for automati-cally determining the instaflts of maximum excitations is designed. The software givessatisfactory result, as judged by calculations and statistics on various Chinese syllablesand the result indicates that the method is highly accurate.
