1 简介

说话人的情感研究是指从说话人的语音信号中提取各种情感因素和情感特征， 判断说话人的 喜怒哀乐， 能够反映出情感特征的物理参数主要反映在发音速度， 振幅， 基频， 频谱变化等方面 变换系统通过 方法提取出基音周期， 然后通过分析得出调整的规则后实行的基音周 期及幅度的修正 ， 最终完成男女声情感变换​。

2 部分代码

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)".
