摘要
在通信领域中,语音信号的研究层出不穷,语音信号处理是以语音语言学和数字信号处理为基础而形成的一门涉及面很广的综合性学科,其中,短时分析给语音信号处理提供了有力的分析方法。本文研究了语音信号的分析方法,即短时能量与短时平均幅度分析、短时过零率分析、短时相关分析、短时傅里叶变换分析,并利用MATLAB对语音信号的短时分析进行了算法实现。
In the communication field, the research of speech signal is emerging. The voice signal processing is a comprehensive subject, including voice linguistics and digital signal processing. Short-time analysis is helpful to voice signal processing. The article analyzes the analyzing method of voice signal, namely short-time energy and short-time average rate analysis, analysis of short-time zero-crossing rate, short-time correlation analysis, shorttime Fourier transform analysis, and uses MATLAB to achieve short-time voice signal analysis algorithm.
