摘要 为了在小数量麦克风阵列的基础上,实现声源的实时定位,给出了一种麦克阵列实时声源定位系统的具体实现方法。这种方法分为时延估计和声源位置计算两步;在时延估计时,采用五帧平均的改进互功率谱相位算法;再根据时延和麦克阵列的四元十字模型计算声源的位置。在实时环境下,距离定位的误差精度低于±20cm,角度的定位误差精度低于±5°。 This paper presents a specific implementation method of real-time sound source location system.The method is divid- ed into two-steps:time delay estimation and calculation of sound source position;apply the improved cross-power spectrum phase algorithm of the average of five frames to time delay estimation;and then calculate sound source position according to the time delay and four quaternary cross microphone array model.In real-time environment,the deviation precise of dis- tance Dositionin~ is less than ~20cm,and the deviation precise of anale Dositioninq is less than ±5°.
