                         noises can appear due to failures in the echo cancellation system. 
                         In order to reduce these noise situations, a novel AEC (Acoustic 
                         Echo Cancellation) system is proposed by using audio and video 
                         information. Through image processing techniques we have developed 
                         a new DTD (Double Talk Detector) based on video information 
                         (video-DTD). A novel Acoustic Echo Cancellation system was 
                         successfully developed, integrating audio and video information. 
                         In simulated results using data from a real scenary the 
                         misalignment of the new AEC (with video-DTD) was smaller than a 
                         traditional AEC.",
