Original Abstract Submitted
example methods and systems provide hybrid dsp-ai acoustic echo cancellation for virtual conferences. a digital signal processing (dsp)-based linear acoustic echo cancelation (aec) can be performed on an input audio signal to filter out linear echo present in the input audio signal and generate a first filtered audio signal. a level of nonlinear echo present in the first filtered audio signal can then be determined. when the level of nonlinear echo satisfies a threshold, an artificial intelligence (ai)-based nonlinear aec can be performed on the first filtered audio signal to generate an ai-filtered audio signal. when the level of nonlinear echo does not satisfy the threshold, a dsp-based nonlinear aec can be performed on the first filtered audio signal to generate a second filtered audio signal.
