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.

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*.
