摘　　要：针对机载强噪声环境下的语音通信,研究并设计基于TMS320VC5509A芯片的语音降噪实时处理系统。对主流语音降噪算法进行研究,采用基于短时谱幅值的频域增强典型算法——谱减法,对带噪语音进行降噪。实验结果表明:该系统具备良好的实时处理能力,在机载强噪声环境下,对带早语音的综合降噪效果较为明显。Aiming at the voice communications in airborne noise environment, research and design real time noise reduction system based on TMS320VC5509A chip. Research on main stream noise reduction system, adopt based on short-time spectral amplitude enhancement typical frequency domain algorithm-spectral subtraction noise reduction for noisy speech. Experiments show that the system has good real-time processing capabilities, strong noise in the airborne environment, you can obtain satisfactory speech noise reduction.
