摘要：
Controlling echo cancellation includes receiving signals associated with a call. A signal of the signals is detected. Whether the detected signal is a high speed signal or a low speed signal is determined. Echo cancellation is disabled if the detected signal is a high speed signal. The echo cancellation is enabled if the detected signal is a low speed signal.
