| Abstract: | 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. |
