Abstract

This paper describes a speech enhancement system (SES) based on a TMS320C31 digital signal processor (DSP) for real-time application. The SES algorithm is based on a modified spectral subtraction method and a new speech activity detector (SAD) is used. The system presents a medium computational load and a sampling rate up to 18 kHz can be used. The goal is to use it to reduce noise in an analog telephone line.

使用TMS320C31数字信号处理器对语音信号进行降噪
本文介绍了一种基于TMS320C31数字信号处理器的实时语音增强系统(SES)。SES算法基于一种改进的频谱减法,并使用了一种新的语音活动检测器(SAD)。该系统具有中等的计算负荷,可使用高达18khz的采样率。目标是用它来减少模拟电话线中的噪音。
