Extraction of Specific Voice in Aircraft Cabin
Yang Hen · Machinery & Electronics · 2014
At the present stage,the identification and analysis of the acoustic signals in Cockpit Voice Recorder(CVR)cannot identify the specific voice in airplane efficiently which ignore the characteristic of the fixed acoustic source in cabin.A method based on Independent Component Analysis(ICA)is proposed to separate acoustic signals in this paper.The simulation is done by Matlab,many groups of experiment data are analyzed by Monte Carlo Method(MCM)to confirm the stability of this algorithm,and the results show that the specific voice is extracted efficiently.
