Transmission of information through the voice of humanity39。s most important, most effective, most popular and most convenient form of exchange of information..Matlab language is a data analysis and processing functions are very powerful puter application software, sound files which can be transformed into discrete data files, then use its powerful ability to process the data matrix operations, such as digital filtering, Fourier transform, when domain and frequency domain analysis, sound playback and a variety of map rendering, and so on. Its signal processing and analysis toolkit for voice signal analysis provides a very rich feature function, use of these functions can be quick and convenient features plete voice signal processing and analysis and visualization of signals, makes puter interaction more convenient . Matlab Signal Processing is one of the important areas of application.The design of voiceprocessing software for most of the content are numerous, easy to maneuver and so on, using prehensive use GUI interface design, various function calls to voice signals such as frequency, amplitude, Fourier transform and filtering, the program interface concise, simple, has some significance in practice.Finally, the speech signal processing further development put forward their own views.Keywords: Matlab， Voice Signal，F(xiàn)ourier transform，Signal Processing目 錄1 緒論 1 1 11. 3本課題的研究?jī)?nèi)容和方法 2 研究?jī)?nèi)容 2 運(yùn)行環(huán)境 2 開發(fā)環(huán)境 22 語(yǔ)音信號(hào)處理的總體方案 3 系統(tǒng)基本概述 3 系統(tǒng)基本要求 3
