一种新的车载系统语音增强算法

New speech enhancement algorithm for vehicle system

本文提出了一种基于麦克风阵列的广义旁瓣抵消语音增强算法,并将其应用于车载系统中。该算法是将固定波束语音增强算法与自适应语音增强算法相结合。仿真结果表明,该算法对加性相干和非相关噪声都有明显的消噪效果,有一定的实际应用价值。

This paper illustrates the generalized sidelode canceller speech enhancement algorithm based on the microphone array,and applied the algorithm for the vehicle system.This algorithm combines the fixed beamforming speech enhancement algorithm and adaptive speech enhancement algorithm.The simulation shows the algorithm has good noise suppression effect to plus correlation noise and non-correlation noise,thus has the practical application value.
