| 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。

| Abstract: | 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. |
