TITLE:THE DESIGN OF PROCESSING SPEACH SIGNAL
Abstract: Speech signal processing is an emerging discipline to study the processing of speech signals with digital signal processing technology and phonological knowledge. It is one of the core technologies in the field of information science research.
MATLAB is a very powerful computer application software for data analysis and processing. It can transform sound files into discrete data files and then use their powerful matrix computing power to process data. Its signal processing and analysis toolbox for the voice signal analysis provides a very rich function easy to carry out voice signal processing.
This topic is based on MATLAB 7.0 using MATLAB integrated GUI interface design, a variety of function calls to achieve the voice signal frequency, amplitude, Fourier transform and filtering functions, simple interface, simple operation has a certain practical significance.
Key words:Voice Signal;MATLAB;GUI;Fourier transform;Filter
