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

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : SRISESHUKUMAR BASAVA; [2012]
   Keywords : MIcrophone array; Wiener beamforming; Source localization;

   Abstract : 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. READ MORE

3. 22. 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

4. 23. Adaptive Speech enhancement system using Linear Microphone-array for noise Reduction

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Jeevan Reddy Yarragudi; [2012]
   Keywords : Speech enhancement; Beam former; Generalized side lobe canceler; LMS algorithm ;

   Abstract : A major part of the interaction between humans takes place via speech communication. It is very difficult to understand speech signals in presence of background noise for the normal listeners and hearing impaired persons. The human speech and hearing organ is inherently sensitive to interfering noise. READ MORE

5. 24. Multi Channel Sub Band Wiener Beamformer

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

   Abstract : 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. READ MORE

6. 25. Intelligent Camera Tracking using SRP-based sound Source localization in frequency domain

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Damodar Reddy Naturi; [2012]
   Keywords : SRP-Phat; acoustics; camera tracking; GCC Phat;

   Abstract : The Steered Response Power Phase Transform (SRP-PHAT) is one of the most robust methods among sound source localization operating in noisy and reverberant environments. Direction of Arrival (DOA) Estimation has important applications in human computer interfaces such as video conferencing, speech enhancement and speech recognition. READ MORE
