摘　　要：分析了同声道语音检测的典型算法SAPVR算法，介绍了算法的基本思想和流程。着重提出了一种简化运算的新的检测算法．用MATLAB工具进行实验，验证了该算法的有效性。Co-channel speech occurs when one speaker＇s speech is corrupted by another speaker＇s speech. A co-channel detection system could provide information to suspend the operation of any speech processing system whose operation would be degraded if it were processing co-channel speech. In this paper we present a new method of co-channel speech detection based on average magnitude difference function （AMDF） transform.
