【语音处理】基于matlab GUI语音信号处理平台【含Matlab源码 218期】

一、简介

本设计针对现在大部分语音处理软件内容繁多、操作不便等问题，采用MATLAB综合运用GUI界面设计、各种函数调用等来实现语音信号的变频、变幅、傅里叶变换及滤波，程序界面简练，操作简便。

二、源代码

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