请录制语音信号集 （不能少于五个语音），然后根据最大似然估计方法，利用MATLAB设计一识别程序，并实现。-Please record a voice signal is set (not less than five voice), then maximum likelihood estimation method, using MATLAB to design a recognition program, and implementation.

基于最大似然估计的独立分量分析算法，包括随机梯度算法，相对梯度算法，快速不动点算法3个程序-Based on maximum likelihood estimation of independent component analysis algorithms, including stochastic gradient algorithm, the relative gradient algorithm, fast fixed-point algorithm for three programs
