Abstract:
A nonlinear acoustic echo signal suppression system and method using a Volterra filter is disclosed. The nonlinear acoustic echo signal suppression system includes an acoustic echo signal estimator configured to estimate a nonlinear acoustic echo signal by using a Volterra filter in a frequency filter, and a near-end talker speech signal generator configured to generate a near-end talker speech signal, in which the nonlinear acoustic echo signal is suppressed, by using a gain function based on a statistical model.
