Abstract: Today, with the development of chip technology and high-bandwidth communications, developers are able to make a fuss about a more superior voice-calling experience, while the demand for hands-free calls is getting higher on the market. However, hands-free communication systems often need to be able to cope with various disturbances. One of the interferences that cannot be overlooked is acoustic echo in the Speaker Echo microphone field (loud
Current results: Speaker read local data, Mic recorded real-time data, can be 90% to eliminate the echo, Aecdelay also need to tune, NS and VAD are normally available. First ensure the AEC normal, next speaker real-time network data, from double talk there is a long way, refueling.
