Description: Feature Selection using Matlab.
The DEMO includes 5 feature selection algorithms:
• Sequential Forward Selection (SFS)
• Sequential Floating Forward Selection (SFFS)
• Sequential Backward Selection (SBS)
• Sequential Floating Backward Selection (SFBS)
• ReliefF
Two CCR estimation methods:
• Cross-validation
• Resubstitution
After selecting the best feature subset, the classifier obtained can be used for classifying any pattern.
Figure: Upper panel is the pattern x feature matrix
Lower panel left are the features selected
Lower panel right is the CCR curve during feature selection steps
Right panel is the classification results of some patterns.
This software was developed using Matlab 7.5 and Windows XP.

Description: 用matlab仿真0到9十个数字的语音识别
1、对语音的WAV文件和LAB文件进行处理，产生十个文件，每个文件对应于一个数字，存贮着该数字的波形文件。（shujuzhengli.m）
2、分别利用上面十个文件训练出十个HMM模板，具体方法是：首先将语音的波形文件分帧，以128个点为一帧，帧移为64，每一帧通过mfcc.m计算出13个系数，随着波形的长度不同，一个语音文件可以计算得到13*N个系数，截取13*15的矩阵（mfcc系数）用作训练数据。一般一个HMM模板用20组mfcc系数训练，得到初始状态分布、状态转移矩阵、高斯正态分布的均值和方差以及混合矩阵，这就是该语音的特征，存贮下来，识别的时候使用。（trainmfcc.m）
3、识别过程：识别的前面部分与训练相似，都是要计算得到mfcc系数，不同在于，识别时，将计算得到的mfcc 参数分别代入训练得到的HMM模板求出概率，比较出最大概率者，则该模板对应的数字就是识别的数字。(shibiesb.m)
4、用大量语音文件做测试，结果正确率为90 以上。-Speech Recogonition: Mumber 0-9

Description: 用头相关传输函数卷积合成虚拟声的方法，我们将利用没有方位信息的单通道声音信号（可以是一段标准语音，也可以是音乐等其他类型的声音），通过信号处理的方法赋予其方位感。
人能听到声音是声音在空间中传播的结果，声音从声源到人耳鼓膜传播过程中发生了变化，这种变化可以看成是人双耳对声音的滤波作用，因此我们将声音从自由场传到鼓膜处的传输函数定义为头相关传输函数(HRTF, Head Related Transfer Function)，其对应的时域响应称为头相关冲激响应(HRIR, Head Related Impulse Response)。本实验用到的HRTF/HRIR数据库是由MIT Media Lab测量得到的。-Convolution with the head-related transfer function virtual sound synthesis approach, we will use the information without bearing single sound signal (can be a standard voice, can also be other types of music, sound), through signal processing methods to give its position sense.
One can hear the sound is sound in space, the spread of the sound the human ear from the sound source to spread the process of tympanic membrane changes, this change can be considered as one of the filtering effect of both ears to the voices, so we will sound from the spread to the tympanic membrane at the free field transfer function is defined as the head related transfer function (HRTF, Head Related Transfer Function), the corresponding time domain response is called head-related impulse response (HRIR, Head Related Impulse Response). The experiment used HRTF/HRIR database is measured by the MIT Media Lab s.
