摘    要:在声源跟踪中,声源定位的精度和更新速率决定了声源跟踪方法的精确度和实时性。常用的声源定位算法易受噪声和混响的干扰,定位精度较差。提出了一种声源跟踪方法,利用语音的线性预测残留误差求互相关对声源定位,减小了噪声和混响对定位的影响。仿真结果显示,该声源跟踪方法有较高的精度和稳定性。

关 键 词:声源跟踪  混响  线性预测  互相关

Abstract:In sound source tracking, the accuracy and data update rate of localization determine the precision and real -time property of the tracking methods. Conventional localization methods are susceptible to noise and reverberation. A moving sound source tracking method based on microphone array measurements is proposed, which uses the speech linear prediction residual to estimate the time delay, and therefore weakens noise and reverberation effect, and significantly improves the positioning accuracy. The robust ...
Keywords:sound source tracking  reverberation  linear prediction  cross correlation
