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。

function varargout = sound_process(varargin)
% SOUND_PROCESS MATLAB code for sound_process.fig
%      SOUND_PROCESS, by itself, creates a new SOUND_PROCESS or raises the existing
%      singleton*.
%
%      H = SOUND_PROCESS returns the handle to a new SOUND_PROCESS or the handle to
%      the existing singleton*.
%
%      SOUND_PROCESS('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in SOUND_PROCESS.M with the given input arguments.
%
%      SOUND_PROCESS('Property','Value',...) creates a new SOUND_PROCESS or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before sound_process_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to sound_process_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
