Abstract: An acoustic echo cancellation (AEC) system includes a remote device, for capturing a remote captured sound, a server coupled to the remote device, and a local device coupled to the server. The server transmits the remote captured sound from the remote device to the local device. The local device receives, stores and plays the remote captured sound as a local playback sound. An echo is generated from reflection of the local playback sound. The local device captures the echo and a local sound into a local captured sound, and transmits both the remote captured sound and the local captured sound to the server. The server performs AEC on the local captured sound by using the remote captured sound from the local device and transmits the AEC processed local captured sound to the remote device.

Abstract translation: 声学回声消除（AEC）系统包括用于捕获远程捕获的声音的远程设备，耦合到远程设备的服务器以及耦合到服务器的本地设备。 服务器将远程捕获的声音从远程设备传输到本地设备。 本地设备接收，存储和播放远程捕获的声音作为本地播放声音。 从本地播放声音的反射产生回波。 本地设备将回声和本地声音捕获到本地捕获的声音中，并将远程捕获的声音和本地捕获的声音传输到服务器。 服务器通过使用本地设备的远程捕获声音对本地捕获的声音执行AEC，并将AEC处理的本地捕获声音发送到远程设备。
