57 Zusammenfassung AB [EN] A speech signal processing system combines acoustic noise reduction and echo cancellation to enhance acoustic performance. The speech signal processing system may be used in vehicles or other environments where noise-suppressed communication is desirable. The system includes an adaptive beamforming signal processing unit, an adaptive echo compensating unit to reduce acoustic echoes, and an adaptation unit to combine noise reduction and adaptive echo compensating.
