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 filters are often used for Acoustic Echo Cancellation (AEC) but sometimes fail to perform well in notebook computers and inexpensive telephony devices. Low-qualit...
