This paper presents a system for full-duplex hands free voice communication integrated with TV technology. The system provides comfortable conversation by utilization of microphone array and advanced voice processing algorithms, even with simultaneous TV usage. Signal processing includes superdirective beamformer steered by direction-finding module, postprocessing module, acoustic echo canceller, stationary noise reduction module and automatic gain control. All processing is realized in real-time on DSP based platform. As communication channel GSM or VoIP can be used.
