  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

  3. 2. Simulation of microphone inaccuracies and robustness analysis of Beamformers inside a reverberant environment

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ADITYA SRI TEJA PALANKI; [2012]
    Keywords : Speech Enhancement; Beamformer; Reverberation; Hearing Aids; Noise Cancellation; Fractional Delay; Binaural hearing; Source localization; Echo Cancellation;

    Abstract : All Speech Processing Equipments like noise cancelling headphones and Hearing aids should be able to filter different kinds of interfering signals and present a clear sound to the listener. The effect of these interfering signals varies depending on the surroundings. READ MORE

    Abstract : The main objective of this thesis, which is a collaborative work between a group of four, is to remove the unwanted components i.e. background noise present in speech signal which affects in the hands-free speech communication. The background noise i. READ MORE

  5. 4. Speech enhancement methods in hands-free communication with emphasis on Optimal SNIR Beamformer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Harish Midathala; [2012]
    Keywords : signal to noise ratio; Beamforming; Reverberated and Anechoic; Speech intelligibility; Reverberation.;

    Abstract : A basic speech enhancement can be achieved by the suppression of background noise and reverberation from the clean speech. The point to be noted is to achieve it with a low computational complexity. The aim is to estimate signal arriving optimally from the desired direction in the presence of reverberant-noisy speech signal. READ MORE
