语音信号的特征量分析和消噪处理
Analysis of speech feature and the treatment of the elimination of noise
【摘要】 介绍了用VC开发的关于语音信号特征量分析及增强的软件包.软件包不仅实现了对语音信号的时域和频域的特征参数快捷提取和实时显示,还可以实现清浊语音段的分离,最重要的是可以实现语音的增强和背景噪声的降低处理.
【Abstract】 In this paper,the software for the analysis and enhancement of speech features with Visual c is presented.This software can gain speech features of time and frequency,Meanwhile,it can draw them.It can also separate the regions of unvoiced and voiced exactly and draw them;It is important that this software can implement speech enhancement processing.
