摘要
在藏语语音处理中基音周期的检测具有非常重要的意义.本文首先讨论了用自相关函数法进行基音周期检测的基本原理及其改进方法,进而研究了这种方法在藏语语音处理中的应用,并给出了相应的实例.
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.
