文章实现了一种基于DSP(Digital Signal Process)的自适应声回波对消系统。该系统通过麦克风收集说话人的语音信号及远端信号通过扬声器-房间通道产生的声回波信号,然后通过自适应算法在DSP中实时的对消掉远端回波信号。
The article realizes an adaptive echo cancellation system based on DSP (Digital Signal Process). The system collects the acoustic echo signal of the speaker’s voice signal and the remote signal through the speaker-room channel through a microphone, and then cancels the far-end echo signal in real time in the DSP through an adaptive algorithm.
