Abstract

Es wird vorgeschlagen, wenigstens einen Akustikaus- mit wenigstens einem Akustikeingang eines Rechnergerätes mit Mehrwege-Akustikaus- und -eingabesystem miteinander zu verbinden und das über diese Verbindung geleitete Akustiksignal einem Acoustic Echo Canceller (F) als ein Referenzsignal zuzuführen für einen Abgleich mit einem Akustiksignal, das dem Acoustic Echo Canceller (F) von wenigstens einem anderen, mit einem Mikrofon (M) verbundenen Mehrwege-Akustikeingang zugeführt ist. Hierdurch ist eine Echofilterung in einem Personal Computer möglich, weil die zugeführten Signale unabhängig von durch das Betriebssystem verursachten Verzögerungen in der Signalverarbeitung stets zeitlich miteinander korreliert sind. Die Echofilterung wiederum ermöglicht das Freisprechen bei einer Spracheingabe.
