Pitch detection plays an important role in Tibetan speech processing.In this paper,Autocorreletion method is introduced,which is a simple and effective method in Pitch detection,but it needs a number of multiplication.Center clipping and three-level clipping are also given,which used to wipe off the effect of track,in order to acquire a more exact pitch period.In addition,the application of this method in Tibetan speech is discussed,and several examples are shown.
