MFCC参数计算，也可进行语音信号处理。 本程序需要调用voicebox工具箱中的melbankm.m程序得到Mel频率滤波器组(MFCC parameters, but also for voice signal processing. This procedure required to call VoiceBox toolbox melbankm.m procedures Mel frequency filter bank)

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.
