Description: 数字音效处理器以MATLAB为设计平台，有.wav文件的获取、滤波、保存和播放功能。在对声音文件进行基本波形分析和频率分析的基础上，增加了特殊音效的功能，并有8段均衡器可对声音信号进行调节后保存播放。此外还附有语音识别程序。-Digital audio processor uses MATLAB design platform,it has wav file access, filtering, saving and playback function. On the basis of sound files for basic waveform analysis and frequency analysis, it adds special effects features, and an 8-band equalizer to adjust the sound signal after saving play. In addition, there s a speech recognition program.

Description: 摘 要：本论文主要研究了语音识别的基本原理,对语音识别系统的构成进行分析处理,其中包括预处理、特征参数提取、建立模块库、识别匹配几大部分。预处理又包括语音采样、预加重、加窗（汉明窗）、端点检测；特征提取的参数是梅尔频率倒谱系数MFCC。
该语音系统采用的是动态时间伸缩算法(DTW)，研究对象是特定人的语音识别，并在MATLAB平台上实现。为了进行后续研究，首先使用电脑中的录音系统录制了阿拉伯数字0—9的语音文件，并转化成 “.wav”格式的文件。-Abstract: This thesis mainly studied the basic principle of speech recognition, to analyze the composition of the speech recognition system, including the preprocessing, feature extraction, to set up the module library, identify several most matches. Pretreatment, including speech sampling, pre-emphasis, add window (hamming window), endpoint detection Feature extraction of MFCC MEL frequency cepstrum coefficient.
The voice system USES a dynamic time scale (DTW) algorithm, the research object is the speaker-dependent speech recognition, and realized in MATLAB platform.To carry out the follow-up study, the first to use the recording in a computer system to record the audio files of Arabic Numbers 0-9, and translated into . Wav format file.

Description: 这是一个matlab程序，该程序的功能是读取一个 .wav 格式的语音信号，画出该语音信号的短时能量。主程序调用了自己编写的两个函数，函数的功能分别是对语音信号进行分帧以及计算每一帧的时间。语音分帧是语音信号处理的关键步骤，该程序可以帮助你快速入门。-This is a matlab program, the function of the program is to read a ' .wav' voice signal format, draw short-term energy of the speech signal. The main program calls two functions I have written, performance function are calculated for each sub-frame and the time frame of the speech signal. Voice Framing is a key step in the speech signal processing, the program can help you get started quickly.
