| Abstract: | 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. |
