  1. 6. Microphone Array Wiener Beamforming with emphasis on Reverberation

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Vamsynagh Pedamallu; [2012]
    Nyckelord :reverberation; wiener; beamforming; PESQ; SRP-PHAT;

    Sammanfattning : Effective speech communication using microphone array is getting significant research in speech acquisition methods such as speaker localization, noise reduction and tracking. To locate the accurate Direction of Arrival (DOA) from the source, it is necessary to design a suitable microphone array system with noise reduction capability as well as efficiency in speaker localization.

  3. 7. Far-Field Wiener Beamforming and Source Localization in Frequency Domain

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sarath Chandra Uppalapati; Deepak Penugonda; [2012]
    Nyckelord :Wiener Beamformer; SRP-Phat; SRK-Phat; Reverberation;

    Sammanfattning : In present conference environments where video recording is required, a set of cameras operated by a human being is needed to track the active speaker as he discusses in the conference. In order to automate this procedure, different methods have been developed in acoustic and visual tracking. LÄS MER

  4. 8. Microphone Array Wiener Beamformer and Speaker Localization With emphasis on WOLA Filter Bank

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Hemanth Yerramsetty; [2012]
    Nyckelord :RIR; Bemaforming; filterbank; srp-phat;

    Sammanfattning : 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. LÄS MER
