Abstract: MATLAB GUI is an interactive environment used by MATLAB users for algorithm development and data visualization. The operation interface generated by GUI enables users to operate without browsing the complicated code. Based on digital signal processing and MATLAB, this paper completes the digital voice tampering detection interface platform from cepstrum analysis by using GUI which is a graphic visualization tool. It records the voice, and studies the changes of time domain waveform, frequency domain waveform, cepstrum map and channel impulse response spectrum when splicing different sampling rates of audio, so as to more intuitively analyze the tampering situation of the voice signal to be detected.

Keywords: MATLAB GUI; voice tampering; audio feature
