57 Zusammenfassung AB [EN] PURPOSE: A system and a method for speech signal processing with combined adaptive noise reduction and adaptive echo compensation are provided to perform both noise reduction and echo canceling very efficiently and allow combined adaptation of an adaptive beam forming unit and an AEC(Adaptive Echo Canceling) unit to simultaneously update both units without occurrence of tracking problems. CONSTITUTION: First speech signals are received, wherein the first speech signals are input signals for an adaptive beam forming employing adaptive beam forming filters. Input signals for an adaptive compensating of acoustic echoes employing adaptive echo compensation filters are received. Combined adaptive filters are determined from the adaptive beam forming filters and the adaptive echo compensation filters. The adaptive beam forming filters and the adaptive echo compensation filters are simultaneously adapted by adapting the combined adaptive filters. Adaptively beam formed signals by the adaptive beam forming are obtained, the echo compensation of the adaptively beam formed signals is performed, and thereby an output signal of speech signal processing is obtained. © KIPO 2006
