摘要
文章实现一种基于麦克风阵列的语音采集增强系统,解决了抑制环境噪声干扰的难点。系统通过多核DSP平台实现,采用麦克风阵列自适应波束形成技术达到增强期望方向的语音,对噪声的抑制采用在方向图上产生零陷,对非相干噪声采用后置自适应滤波技术,能极大地提高系统采集语音的性能。
A new system for speech enhancement based on microphone array is proposed in this paper. The difficulty of suppressing environmental noise is solved in the system. The system is built on multi-core DSP platform, using beamforming techchnoology with microphone arrays, which produces null steering for normal noises in the space map and filtering coherent noises by adaptive filtering technology. The system improves the performance of voice acquisition system.
