Experimental results show that,compared with traditional double-talk detection methods,the new algorithm has comparable computation complexity and works more stably,thus improving the echo return loss enhancement(ERLE) during the double-talk.

• 实验结果表明,该算法与传统算法相比,运算量相当; 但在双端发声期间,该算法稳定性更高,回音往返损耗增强(E cho return loss en-hancem en t,ERLE)有明显的改善。
