基于计算机声卡的谱相减语音增强系统分析

Computer-based sound card for spectral subtraction speech enhancement system

计算机声卡是多媒体技术中最基本的组成部分,是实现声波/数字信号相互转换的一种硬件。对基于计算机声卡的谱相减语音增强系统进行分析。首先分析了基于计算机声卡的语音增强系统,其次,介绍了谱相减算法,具有一定的参考价值。

Multimedia computer sound card is the most basic part of the realization of acoustic / digital signal conversion between a piece of hardware.In this paper,based on computer sound card＇s spectral subtraction speech enhancement system for analysis.First analysis of computer-based speech enhancement systems sound card,Then,the spectral subtraction algorithm,with some reference value.
