Abstract
A method of pitch mark determination for a speech, includes: acquiring a fundamental frequency point and fundamental frequency passband signals by using an adaptable filter; detecting a number of passing zero positions of the fundamental frequency passband signals; and generating at least a set of pitch marks from a number of passing zero positions. Lastly, estimating several sets of pitch marks generates the best set of pitch marks.
