Abstract
A system and method that enhances spoken utterances by capturing one or more microphone signals. The system and method estimates a plurality of echo paths from each of the one or more microphone signals and synthesizes a speech reinforcement signal in response to and corresponding to the one or more microphone signals. The system and method concatenates portions of the synthesized reinforcement signal with the captured microphone signals and processes the captured microphone signals in response to the estimated plurality of echo paths.
