This paper aims at double-talk detector design for acoustic echo cancellers (AECs) enabling transmission of speech signals in stereo. A reliable double-talk detector (DTD) is often a necessary requirement for AECs. Its role is to freeze the adaptation of the AEC filter when near-end speech is present in order to avoid divergence of the adaptive algorithm. The existing DTDs based on the normalized...
A reliable double-talk detector (DTD) is often a necessary requirement for acoustic echo cancellers (AECs). Various techniques have been proposed in the literature to detect double-talk for AEC systems. In those DTD algorithms, the acoustic echo path is assumed to be linear. On the other hand, nonlinear AEC is necessary when the system components such as loudspeakers exhibit nonlinearities. In this...
