实现 直接2型滤波器的设计 以及 仿真 功能

通过语音识别来控制程序的运行，支持英文。-Using speech recognition technology to control the runing of program. (English version)

检测语音信号的共振峰 ％ gender = gender_detector(X,Fs) ％ ％ This function will use a pitch detection algorithm to decide if the speaker is MALE(0) or FEMALE (1). ％ It is designed to work with short speech samples (up to or greater than 50 ms). The function returns a ％ 0 if X contains male speech and a 1 if it contains female speech. -the resonance peak gender_detector% gender = (X, Fs)%% This function will use a detection a pitch lgorithm to decide if the speaker is abbreviation (0) or F EMALE (1). % It is designed to work with short spe ech samples (up to or greater than 50 ms). The fun ction returns a 0% if X contains a male speech and if it contains a female speech.

基于matlab的信号FFT实现与分析，通过matlab实现-Matlab-based signal with FFT analysis, to achieve through matlab

语音识别，能量计算，过零率检测，发生点检测，用于音符切分-Speech recognition, energy calculation, zero-crossing rate detection, point detection occurs for note segmentation

采用MELP编制的压缩与解码程序，在MATLAB环境下可直接运行，语音2.4kb/s-MELP (Mixed-Excitation Linear Predictive) Vocoder is a new 2400 bps Federal standard speech coder. This Matlab code of MELP can run directly in MATLAB condition.

这是一个语音程序-This a procedural voice!

自己编写的用于传感器信号滤波的算法程序，并有真实信号处理的数据演示-I have written for the sensor signal filtering algorithms procedures and have the authentic signal processing of data presentation

这是一个字符识别程序，主要利用关系码和方向码来识别汉字或者英文字符的手写识别-This is a character recognition procedures, using mainly between code and code to identify the direction of Chinese or English characters handwriting recognition

采样小波包分解语音信号，分解为3层，并求出分解系数-Speech signal using wavelet packet decomposition，decomposing 6 level，and attain decomposition coefficient

求语谱图的matlab程序，非常有用-Spectra for the matlab language program, very useful
