Abstract
One of the most important signal processing method in Digital Signal Processing discipline is Speaker Identification Method (SIM). Because of the difficult nature of speech signals and their fast variation with time, the wavelet transform is used to reduce the complexity of such signals. In this paper two identification methods are presented based on Continuous Wavelet Transform CWT. The first method is the male and female identification method and the second is the SIM. The obtained results showed a high recognition rate about 98%, which makes the speaker identification wavelet transform based method to be very important in digital security systems applications.
