| Abstract(in English) | This paper proposes a new nonlinear-echo model based on spectral correlation between the residual echo and the echo replica in an ordinary echo canceller, and a new echo suppressor based on the model. First, it is revealed by experiments that there is a significant correlation between the spectral amplitudes of the residual echo and the echo replica, and a new model for nonlinear-echo suppression based on the correlation is derived. Next, a new echo suppressor controlling the gain in each frequency bin to suppress the residual echo based on the new model is developed. Simulation results with speech data recorded by a hands-free cellphone show that the proposed echo suppressor reduces the residual echo to an almost inaudible level. |
