摘要：
This paper presents a new double-talk detection algorithm which is based on the orthogonality theorem. The unique feature of this algorithm is that it does not only prevent the echo canceller from being disturbed by double-talking but also quickly track the echo path variations. The nice properties of this algorithm are confirmed by computer simulation.
