中文摘要：

Matlab是一款功能强大的数学软件，它附带大量的信号处理工具箱，如sptool、fdatool、wavelet、simulink工具箱等，为信号分析研究，特别是文中主要探讨的声波分析研究带来极大便利。声音的特征可用声压强，频律等各种参数描述，文中主要探究声音在频率上体现出的各种特性，并在此基础上在Matlab平台下对声纹识别技术做初步探索。

英文摘要：

Matlab is a powerful mathematic software with a mass of toolboxes dealing with signal processing, like ＇ sptool＇ , ＇ fdatool＇ , ＇ wavelet＇ , ＇ simulink＇ etc. It gives a terrific shortcut to the research of signal processing,especially the wave analysis. The sound was characterized with key parameters such as intensity, frequency etc. and the experiment was based on Matlab 7.0 to make a general research of the relations between voice and frequency. Besides, to have a simple exploration of the voice recognition is another target.
