  • Publication number: 20140329568
    Abstract: An echo canceller and an echo cancellation method are provided. The echo canceller includes a self-adaptive filter, a voice signal detection portion and a path change detection portion; a far-end voice signal is propagated in an echo path through a speaker and is picked up by a microphone to form an echo signal. The self-adaptive filter is configured to receive the far-end voice signal as a training signal to simulate the echo path, and cancel the echo signal in a near-end signal. The voice signal detection portion is configured to detect a communication status, control the self-adaptive filter according to the communication status, and control startup of the path change detection portion according to the communication status. The path change detection portion is configured to detect whether a change occurs on the echo path, and control the self-adaptive filter according to whether the change occurs on the echo path.
