代码说明:

此代码使用 speakerr 鉴定。在这项工作,我用 MFCC 作为特征提取和我用支持向量机作为分类器。这段代码是非常有用的信号处理工作的人。MFCC 计算中很多步骤,第一,划分信号的帧,然后每个帧乘以海明窗后, 我们将快速傅里叶变换应用于每个帧。然后,Mel 滤波器已经被应用到照片。离散余弦变换和门窗升降器应用于结果。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    说明:  使用单例模式封装了多语言处理类,json文件存储多语言关系,用后期用户可自行多语言翻译,每个页面初始化时添加多语言初始即可,自动把窗体内的所有控件进行多语言处理,可自定义对特殊控件的特殊处理,集中管理,方便快捷。(It uses singleton mode to encapsulate multilingual processing classes, JSON files to store multilingual relations, and later users can translate multilingual by themselves. When each page is initialized, multilingual initial can be added. All controls in the form can be automatically processed in multilingual. It can customize the special treatment of special controls and centralize management. Quick and convenient.)
