摘　　要：设计和开发了一种基于MATLAB的语音采集与分析的可视化系统,该系统通过Realtek Ac'97型声卡和MATLAB的数据采集工具箱低成本地实现了语音信号的实时采集,并利用MATLAB强大的数值计算和信号处理功能高精度地完成了语音信号的分析工作。系统还使用MATLAB的图形用户界面设计工具进行了优化,通过简单的对话框和菜单操作取代了复杂的程序修改和调试过程,使得系统的使用更加方便灵活。A kind of visual audio signal acquisition and analysis system based on the MATLAB is designed and developed. The system has realized the real-time audio signal acquisition at a lower cost by the sound card of Realtek Ac＇97 and MATLAB＇s Data Acquisition Toolbox, and accomplished audio signal analysis with high precision using MATLAB＇spowerful calculation and signal pmcessing abilities. The system is optimized by MATLAB＇s GUI, which takes advantage of simple dialog box and menu operation instead of complex program modification and debugging,and makes the usage of the system more convenient and flexible.
