Patent ID: 8923509

Claim:
A method comprising: receiving, at an echo canceller device, an incoming voice signal from a remote source in a wideband conference, wherein the incoming voice signal includes a low band and a high band, the echo canceller device being configured to receive both the high band and the low band; detecting a double talk condition at the echo canceller device, wherein the double talk condition is due to a local voice signal being originated by a local user at a same time the incoming voice signal is received; based on detecting the double talk condition, processing, by the echo canceller device, the incoming voice signal and the local voice signal such that an echo is reduced in an outgoing voice signal that includes the local voice signal, wherein the echo is due to a reflection of the incoming voice signal, and wherein the processing comprises: disabling an attenuation of the outgoing voice signal, enabling a high frequency processor for removing the high band from the incoming voice signal such that echo due to the high band is not generated, the high frequency processor allowing the low band associated with the incoming voice signal to pass through the high frequency processor, and canceling, without use of an adaptation signal, an echo generated due to the low band associated with the incoming voice signal that is passed through the high frequency processor.
