| Abstract: | The paper adopts the strategy of modular design and schemes out the signal producing modular, the signal collecting modular, and some signal-processing-related modulars including the wave display, frequency analysis, signal filter, etc. The use of LabVIEW in the programming helps to build the above modulars on the basisi of the LabVIEW developing platform and shows the front paneal picture and the procedure flowchart of the speech signal analysis. The system of these virtual instruments in the thesis is specially designed to analyze and process the speech signal systermaticly. |
