Abstract

Double-talk (DT) detection schemes for echo cancellation based on energy comparison and cross-correlation algorithms are presented. It was found that the correlation-based algorithms show improved detection performance in such time-varying environment. These algorithms however require high memory storage and computational complexity due to vector or matrix-based operations. The energy-based algorithms are computationally simple, needing very little memory, but they do not always provide reliable performance in an acoustic echo path environment.
