基音周期是语音信号最重要的参数之一,它描述了语音激励源的一个重要特征。被广泛应用到语音合成、语音识别等领域。本文介绍了一种基于AMDF的语音基音周期检测方法,较好的提取了语音的基音周期。
Pitch is one of the most important parameters in phonetic signal.It describes an important character of phonetic excitation source. Pitch applies widely to phonetic synthesis and phonetic recognition fields and so on. The thesis introduces an AMDF-based method that the effect of pitch detection is preferable.
