Abstract :
This paper describes the pitch detection techniques and voiced/unvoiced decision using normalized cross correlation function (NCCF) method and circular average magnitude difference function (CAMDF) method involving the preprocessing and the post processing. Major innovations include: The pitch period candidates selection based on NCCF and CAMDF, the simple and easy to implement post processing based on local speech segment. It also presents the basic experiments and discussions.
