Tele - conference, video - conference. acoustic echo cancellation is normally achieved by means of an acoustic echo canceller, which, in its simplest form, consists of an adaptive filter which mimics the transfer function of the echo path ( or room acoustic ) to synthesize a replica of the echo, and then subtracts the estimation from the combined echo and near - end speech ( or disturbance ) signal to obtain the near - end signal alone
聲回波抵消通常採用聲回波抵消器來實現，最簡單的聲回波抵消器由自適應濾波器組成。具體方法是用自適應濾波器來估計回波信號，並從麥克風信號中減掉該估計值，從而實現聲回波的抵消。
