  1. 1. Speech Enhancement in Hands-Free Device (Hearing Aid) with emphasis on Elko's Beamformer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : TELAGAREDDI S N U V RAMESH; [2012]
    Keywords : Speech Enhancement; Speech intelligibility; Speech Communication and Beamforming ;

    Abstract : In general, an uncontrolled environment may contain degradation components like background noise, speech from other speakers etc. along with required speech components. It is very tough to concentrate only on speech signals in presence of background noise for normal listeners and hearing impaired persons. READ MORE

  6. 5. An Array of First Order Differential Microphone Strategies for Enhancement of Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Naresh Reddy NagiReddy; Arun Kumar Korva; [2012]
    Keywords : speech enhancement; beamforming; microphone array; elko algorithm; wiener beamformer; differential microphone ;

    Abstract : The quality and intelligibility of speech is degraded with the presence of background noise in the speech signal, which affects the listeners ability to understand the speech clearly. Speech enhancement is the process with which the background noise can be suppressed to improve the quality and intelligibility of the speech signal. READ MORE
