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.)

kmeans特征提取
应用背景利用kmeans进行聚类后,一般就结束了。但是有些论文提出,其实kmeans聚类完成后得到聚类中心,根据样本离聚类中心的距离构建特征。将这个特征用于物体分类。物体识别的效果都比不逊色其他复杂的特征。因此kmeans特征提取值得研究。关键技术kmeans聚类的时候关于k的取值是一个关键的调参问题。kmeans聚类完成后,可以有两种特征提取的方法,一种是硬分配方法,一种是三角分配方法。两种方法对比,三角分配法得到的特征更加鲁棒。在用于物体识别或者物体分类的应用中有着不逊色的结果。
