  1. 16. 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. 17. 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

  5. 19. Microphone Array Wiener Beamformer and Speaker Localization With emphasis on WOLA Filter Bank

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Hemanth Yerramsetty; [2012]
    Keywords : RIR; Bemaforming; filterbank; srp-phat;

    Abstract : This thesis describes the design and implementation of a speech enhancement system that uses 4-channel microphone array beam forming and speech enhancement algorithms applied to a speech signal in a multiple source environment. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with more efficient localization algorithm. READ MORE
