Abstract
A system and method is disclosed to remove cross talk terms from speech signals in a multi-party conference system using an estimator to first estimate the respective cross talk terms for each of the said plurality of users. In one embodiment, these terms are then multiplied with a filter based on the estimated cross talk terms. Source speech signals may thereby be recovered from the plurality of multi-party conference users without the cross talk.
