Echo cancellation problems in Automatic Speech Recognition (ASR) systems are not mere annoyances; they can destroy the accuracy, usability, and value of an ASR system, as well as directly reduce customer satisfaction. That is why developers should give additional thought to ensuring that echo cancellation performance is effective under all anticipated circumstances. This white paper will identify special considerations for echo cancellation in ASR systems, examine how echo is created, and describe approaches to eliminating it.
