【语音处理】基于matlab GUI音频信号处理（调音+调速+调频+滤波）（带面板）【含Matlab源码 299期】

一、语音处理简介

MATLAB GUI是用户与计算机或计算机程序的接触点或交互方式,是用户与计算机进行信息交流的方式。图形用户界面（Graphical User Interfaces,GUI）则是由窗口、光标、按键、菜单、文字说明等对象（Object）构成的一个用户界面。用户通过一定的方法（如鼠标或键盘）选择、激活这些图形对象,使计算机产生某种动作或变化,比如实现计算、绘图等。本设计基于MATLAB GUI技术,完成了语音信号处理的界面平台,可进行语音的选取、线性预测分析（LPC）、语谱图、频谱等相关波形的显示。这样可以更直观、更方便地分析和处理语音信号,得到用户需要的实验结果。

二、部分源代码

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