基于MATLAB的GUI设计

GUI design based on MATLABAbstract:With inprovements in science and technology,speech recognition technology is widely usedaround us,such as artificially synthesizing speech,recognizing content or distinguishing speakers,butgenerally faces the problem of noise causing interference to the signal.Based on the above,this design mainly focuses on the acquisition,noise and filtering of voicesignals,and designs a GUI interface simulation system based on the acquisition and analysis of voicesignals on MATLAB software.A pre-recorded sound is imported into the system with.Wav,and afterthe voice signal is collected,Fourier transform is performed,random noise is added,and the noisesignal is filtered with batworth low-pass filter,and corresponding time-domain and frequency-domaingraphs are obtained respectively.Through testing and analysis and comparison,and calling the functionto realize the programming code,the simulation interface of the system is finally realized,and theoriginal sound is played.The advantages of this design are that the GUI is composed of Windows,pop-up boxes,buttons,dynamic text boxes and other interface forms with strong demonstration and visibilityKey words:voice signal,MATLAB,acquisition and analysis,GUI
