  1. 1. Microphone Array Wiener Beamforming with modeling of SRP- PHAT for Speaker Localization

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :SRISESHUKUMAR BASAVA; [2012]
    Nyckelord :MIcrophone array; Wiener beamforming; Source localization;

    Sammanfattning : The use of microphone arrays to acquire and recognize speech in meetings (conference) poses several problems for speech processing as there exist many speakers within a small space, typically around a table. The necessity to design a suitable microphone array system with minimum noise and more efficient localization algorithms is drawing attention of researchers to work on it. LÄS MER

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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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. LÄS MER

  4. 3. Multi Channel Sub Band Wiener Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Rajesh Amerineni; [2012]
    Nyckelord :Reverberation; Linear Microphone array; WOLA Filter Bank; Wiener Beamformer; SRP-PHAT;

    Sammanfattning : With the recent advance in microphone array speech processing, achieving robustness of speaker localization becomes most significant aspect. At the same time considerable research growth is performed in developing the multiple microphone sensors equipped rooms are developed also called as smart rooms for real time applications. LÄS MER

  5. 4. 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.
