Abstract
随着现代计算机科学技术的不断发展，labview图形编程开发技术已经被广泛应用。针对数据采集卡采集语音信号数据成本过高和计算机声卡性价比高等优点设计了基于labview的声卡数据采集处理系统。该系统可以根据用户需要设置合适的采样参数对采集到的语音信号进行时域和频域上的分析。该系统具有界面设计简单，扩展性好，功能多样化和数据处理能力强等优点。 With the development of modern computer science and technology, Labview graphical program-ming technology has been widely used nowadays. Considering the cost of the data acquisition card is high and the computer sound card is cost-effective, data acquisition card can be replaced by computer sound card. According to this we designed a sound card based on Labview data acquisi-tion processing system. This system can meet users’ different demands. We can do research on speech signal in time domain and frequency domain by setting appropriate sampling parameters. This system’s interface is simple and it has good expansibility, functional diversity and strong data processing capability.
