摘要
双通道语音增强技术在自适应噪声对消系统中有着广泛的应用。在传统的双通道自适应噪声对消系统里,需要一个纯净的参考噪声作为辅助输入,但这在实际应用中很难做到。首先针对基本的自适应噪声对消原理,研究了一种改进的双通道自适应语音增强模型。该模型是一个基于TMS320C6713B芯片的双通道实时数据处理系统,以AD73311为数模转换器件,具有两路独立的A/D、D/A通道,能够实现语音信号的16位数据采集与处理。最后对此系统的DSP硬件设计作了简要介绍,并研究了该系统的软件设计以及算法实现。
The two channel speech enhancement technology is widely used in adaptive noise cancellation(ANC)systems.Pure reference noise is demanded as auxiliary input in traditional two channel ANC systems,but it is hard to implement in actual environment.Based on the basic principle of ANC,this paper presents a modified model of two channel adaptive speech enhancement.This model is a two channel real time data processing system based on TMS320C6713B,with AD73311 as its converting device.It includes two separate A/D,D...
