In the GUI graphical user interface, a simple manmachine interactive operation to achieve the digital voice signal waveform, spectrum analysis, and highpass, low pass, band pass, band stop filter analysis and processing. In the Simulink simulation system, the digital speech signal corresponding dynamic and static analysis of treatment simulation. Simulation principle of this paper is simple, easy to implement, when the need for more plex speech signal processing and analysis functions can be expanded further on the speech signal analysis and processing has to learn from the meaning.
