Double-Talk Detection for Stereophonic Acoustic Echo Cancellation in a Time-Varying Environment Proceedings of the 25th Electrical Engineering Conference (EECON'2002, Prince Songkla university, Thailand), November 2002. |
Abstract
In this paper, a Double-Talk (DT) detection method is introduced for Stereophonic Acoustic Echo Cancellation (SAEC) in a time-varying environment. The proposed DT detector employs the generalized likelihood ratio (GLR) method and aims to distinguish between the DT situation and the abrupt change in the acoustic echo paths (ACAEP). Simulation results based on coloured noise sequences support these ideas.
