ECHO CANCELLATION Echo Cancellation is used in telephony to describe the process of

removing echo from a voice communication in order to improve voice quality on a telephone

through silence suppression by preventing echo from traveling across a network. There are

two types of echo of relevance in telephony: acoustic echo and hybrid echo. Speech

compression techniques and digital processing delay often contribute to echo generation in

telephone networks.
