基于球麦克风阵列的语音增强方法

摘要

Interference noise suppression can be affected based on the regular beamforming method to some degree when the desired source and interference noise source are in the same direction. The method was presented based on chebyshev radial filter to implement speech enhancement under the premise of knowing the sound source position information, combining spherical microphone array beamforming with radial filtering. Simulation results showed that the method achieves the enhancement of the desired source, and is also proved in the effectivity to a certain degree.%当期望源与干扰噪声源同向时，常规波束形成方法对干扰噪声的抑制会受到一定的影响。在已知声源方位信息的前提下，将球麦克风阵列波束形成和径向滤波相结合，提出一种用切比雪夫径向滤波实现语音增强的方法。仿真实验结果表明，该方法实现了对期望声源增强的目的，从一定程度上验证了该方法的有效性。
