Abstract：There is a larger sound reverberation phenomenon because of a narrow space in aircraft. The reverberation signal influences call quality when crew don’t wear the special earphone for voice calls within the aircraft. The use of a sound source location signal for speech enhancement can suppress reverberation interference to achieve better call effect. Due to the influence of reverberation, common sound source localization algorithm is very difficult to take effective location to the voice of the crew. Through studying the speech transmission characteristics of the space aircraft, beamforming algorithm based on correlation coefficient is proposed and uses the waveform similarity to suppress reverberation interference. Experimental results show that the algorithm has better effect of sound source localization to supply source orientation parameters for speech enhancement.
