Echo cancellation/suppression and double-talk detection in communication paths |
摘要 |
A method of suppressing an echo signal in a communication path such as acoustic coupling between a speaker and a microphone in a telephone device handset includes the steps of monitoring a transmitted signal supplied to the communication path to determine an attribute thereof; generating a leaky mask based on the determined attribute and an attribute of a received echo signal; and partially cancelling the received echo signal using the leaky mask.
