中文说明：借鉴了主成分分析算法（PCA），部分实现了追踪测速迭代松弛算法，已调制信号计算其普相关密度，大学数值分析算法，实现了对10个数字音的识别，使用起来非常方便。
English Description：
Using principal component analysis (PCA) algorithm, part of the implementation of the tracking velocimetry iterative relaxation algorithm has modulated signal calculated relative density of its universal, University of numerical analysis algorithm to achieve the recognition of 10 digital sound, very convenient to use.
