  3. 7. MICROPHONE ARRAY SYSTEM FOR SPEECH ENHANCEMENT IN LAPTOPS

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : NAVEEN KUMAR THUPALLI; [2012]
    Keywords : Wiener Beamformer; Speech Enhancement; Generalized side lobe canceller ;

    Abstract : Recognition of speech at the receiver end generally gets degraded in distant talking atmospheres of laptops, teleconfereing, video conferences and in hands free telephony, where the quality of speech gets contaminated and severely disturbed because of the additive noises. To make useful and effective, the exact speech signals has to be extracted from the noise signals and the user has to be given the clean speech. READ MORE
