1 简介
语音信号处理技术是语音处理领域中新近发展起来的一个学科分支,MATLAB是一个数据分析和处理功能十分强大的工程实用软件,运用它来进行语音信号的采集,分析和处理相当便捷.文章介绍了在Matlab环境中如何采集语音信号和语音信号采集后的频谱分析处理,并通过实例分析了语音信号处理的Matlab.
2 部分代码
function varargout = untitled(varargin)
%
UNTITLED MATLAB code
for
untitled.fig
%
UNTITLED, by itself, creates a new UNTITLED or raises the existing
%
singleton*.
%
%
H = UNTITLED returns the handle to a new UNTITLED or the handle to
%
the existing singleton*.
%
%
UNTITLED(
’CALLBACK’
,hObject,eventData,handles,...) calls the
local
%
function
named CALLBACK
in
UNTITLED.M with the given input arguments.
%
%
UNTITLED(
’Property’
,
’Value’
,...) creates a new UNTITLED or raises the
%
existing singleton*. Starting from the left, property value pairs are
%
applied to the GUI before untitled_OpeningFcn gets called. An
%
unrecognized property name or invalid value makes property application
%
stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
%
*See GUI Options on GUIDE
’s Tools menu. Choose "GUI allows only one
%
instance to run (singleton)".
