Abstract
A method of pitch mark determination for a speech includes the following steps. First, a fundamental frequency and fundamental frequency passband signals are acquired by using an adaptable filter. Then, a number of passing zero positions of the fundamental frequency passband signals are detected. After that, at least a candidate set of pitch marks from a number of passing zero positions are generated. Lastly, the candidate set of pitch marks is estimated to generate the best set of pitch marks.
