Description: （1）录制语音文件
利用GoldWave或NGwave录音软件录制单字发音语音文件，以wav音频格式保存，共录制两组，一组用于计算参考模板，另一组作为测试模板用于语音识别。
录制语音时，为了能够在主程序中循环读入语音文件，文件名采用数字顺序命名。记录语音文件以及所对应的发音。记于表3中。
另外，录制语音时，注意调整合适的Mic音量，避免语音波形幅度过小，难于同噪声区分开。同时也要避免波形幅度过大，造成波形失真。
（2）调试端点检测程序
结合流程图读懂Matlab程序，先单独调试，记录并观察测试结果。
原始语音中检测出起始和终止端点后，用plot( )函数绘制原始语音文件波形图，检测得到的端点之间的语音波形图。对比图形，分析检测结果是否满意。
（3）调试DTW主程序
结合图3.2所示流程图修改和调试Matlab程序，加入DTW实验系统工具箱文件，调试运行程序。
（4）运行和测试系统
先把录制好的声音文件（自己录制的和其他同学录制的）制作成2组声音文件，再准备两个测试音文件。

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.
