<p>The invention includes a method and apparatus for detecting and suppressing echo in a packet network. A method according to one embodiment includes extracting voice coding parameters from packets of a reference packet stream, extracting voice coding parameters from packets of a target packet stream, determining whether voice content of the target packet stream is similar to voice content of the reference packet stream by processing the voice coding parameters of the reference packet stream and the voice coding parameters of the target packet stream, and determining whether the target packet stream includes an echo of the reference packet stream based on the determination as to whether the voice content of the target packet stream is similar to voice content of the reference packet stream.</p> |
