把一个人的声音变成别人的声音有二种：一种是：将一个人的声音，变成非特定人的声音，如：把男声变女声，或把小孩子声音变成老人声音。另一种是：将一个人的声音变成特定人的声音，有点像美国电影中那种，A可以通过就变音技术说出B的声音。
此技术应用领域：一是娱乐性的，如：聊天的最高声音---变音聊天。 二是：有关保密方面，如某长官发布命令，在传播过程中进行变音，让敌方猜不出已方的领导人的身份。三是：被坏人利用。哈哈！
一、变音一般性的描述：
朋友们平常网上聊天大多是打字聊天! 即累又费时!稍微流行点的就是使用麦克风"摄像头类的东东改变一下聊天的氛围!另类的聊天境界你体验过吗？ 那就是可以将自己语音聊天时的声音更换的更有个性!比如：将自己极具磁性的声音，打造成一个极甜美的声音!怎么样!好玩吧？
一般的音频可以借助电脑声卡的设置再加一软件配合就能实现。
二、变音的主要算法原理
简单说几种：
最简单的是：通过对语音的采样率进行变化，就能改变声音，这种是最低的，且不易用参数进行控制。
别外一种是：提取反应该个性的参数，如，男人、女人；小孩和老人，因声道的长度不一样，导致其基音不一样，进而导致各谐振峰不一样。我们可能通过改变基音和谐振峰的位置来改变声音。
