Abstract: In view of problems of complex code program and poor portability in programming method of traditional digital filter, the paper proposed a design scheme of digital filter for voice noise based on LabVIEW. The filter uses graphical programming language LabVIEW 8.6 to realize functions of voice signal filtering, real-time measurement and storage, alarm, which has characteristics of low development fund, simple development process, convenient extend function and easy operation and usage compared with traditional filter.
