摘要
本文介绍了小波变换用于信号突变的检测原理，给出了实现小波变换的快速算法。语音的基音检测作为一个应用实例，在文中得到验证。理论与实验表明，利用小波变换检测基音与传统方法相比具有独到之处。
This paper describes the principle of singularity detection of signals with wavelet transform.A fast algorithm is developed for computing wavelet transform of signals.A pitch detector,used to estimated the pitch period of speech signals,is taken as example to show the practical application of the principle.Some experimental results are provided to show the advantages of the pitch detector.
