一、简介

基于matlab GUI语音基频识别，先进行语音采样，变速、重采样。

二、源代码

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