A system approach to residual echo suppression in robust hands-free teleconferencing
This paper presents a system approach to the residual echo suppression (RES) problem in a noisy acoustic environment. We propose a method that takes advantage of our existing robu...

Postfiltering for Suppression of Residual Echo from Vocoder Distortion in Packet-Based Telephony
This paper investigates postfiltering for residual echo suppression in networks employing low-bit-rate speech compression in the echo path. Simulations show that the residual echo...

Nonlinear residual acoustic echo suppression for high levels of harmonic distortion
Linear adaptive ļ¬lters are often used for Acoustic Echo Cancellation (AEC) but sometimes fail to perform well in notebook computers and inexpensive telephony devices. Low-qualit...
