An echo suppressor attempts to determine which is the primary direction and allows that channel to go forward. That is one person speaks while the other listens. In essence these devices rely upon the fact that most telephone conversations are half-duplex. In the earlier days of telecommunications, echo suppression was used to reduce the objectionable nature of echos to human users. If the delay is very small (10's of milliseconds or less), the phenomena is called sidetone and while not objectionable to humans, can interfere with the communication between data modems. On a telephone, if the delay is fairly significant (more than a few hundred milliseconds), it is considered annoying. The echo is a delayed version of the original.

Echo is the reflected copy of the voice heard some time later. In telephony, 'Echo' is very much like what one would experience yelling in a canyon. Echo cancellation is done using either echo suppressors or echo cancellers, or in some cases both. This technique is generally implemented using a digital signal processor (DSP), but can also be implemented in software. Once the echo is recognized, it can be removed by 'subtracting' it from the transmitted or received signal. Speech compression techniques and digital processing delay often make these echoes more severe in telephone networks.Д®cho cancellation involves first recognizing the originally transmitted signal that re-appears, with some delay, in the transmitted or received signal. Two sources of echo have primary relevance in telephony: acoustic echo and hybrid echo. In addition to improving subjective quality, this process increases the capacity achieved through silence suppression by preventing echo from traveling across a network.
