The typical time-frequency characteristics and core processing algorithms of speech signals are key issues in speech recognition, synthesis and speaker recognition systems. Combining the algorithm principles of linear prediction analysis technology (LPC) and Mel Cepstral Parameters (MFCC), based on MATLAB GUI technology, an interface platform for the typical feature extraction system of speech signals was designed, which can realize the functions of loading, playing and waveform display of speech signals, display of LPC and MFCC calculation results and data storage.
