Abstract
Acoustic echo control has become an important feature in modern speech processing systems, such as hands-free telephones, multi-channel teleconferencing systems, public address systems, car interior communication devices, hearing aids and voice recognition systems. This paper presents an overview on applications of acoustic echo control, explains the boundary conditions of these applications and shows recent solutions. For some selected applications (hands-free telephones and car-interior communications systems) results achieved with real systems are presented.
