Abstract
A device for reducing echo by controlling microphone and/speaker gain in a telecommunications system is disclosed. An exemplary embodiment of the device may have an echo detector, echo level detector, and a gain controller. The echo detector detects an echo in a transmitted audio communication signal. The echo level detector determines the volume level of the detected echo. The gain control may adjust the gain of a microphone transmitting and/or speaker broadcasting the audio communication signal based on the echo level detected. The gain control and echo cancellation may cooperate with each other.
