耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

说明：  简单实用的matlab程序实例，大家有什么不懂的可以问我啊(Matlab procedure simple and practical examples, we can not understand what asked me ah)

FIR带通滤波器，用于分离混叠信号，适用于初学者(FIR band-pass filter, used to separate overlapping signals for beginners)

通过应用高斯混合模型来实现语音识别，语音样本为短时语音(By applying a Gaussian mixture model to achieve speech recognition, voice samples of short-time speech)

Module PV usning Simulink

这是一个很基本的pso算法的matlab的源码。比较的简单，但是可以再这个基础上修改的(This is a very basic PSO algorithm matlab source code. Comparison of the simple, but can be modified based on this)

说明：  矩阵，尤其是分块矩阵的分解，删除，调整，可以方便数值计算，减少冗余(Matrix, in particular, block matrix decomposition, delete, adjust, easy numerical calculation, to reduce redundancy)

采用matlab语言编写的用内点法罚函数解决问题的方法。(The MATLAB language is used to solve the problem by using the penalty function of the interior point method.)
