1. 6. Source Localization and Speech Enhancement for Speech Recognition for Real time Environment

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Asim Muhammad; Akbar Ali; [2012]
   Nyckelord :Beamforming; Localization; Lapped Transform; SRP-PHAT; MVDR; Subspace Supression; PESQ;

   Sammanfattning : Popularity of speech communication is rapidly increasing in various contexts such as conferencing systems, mobile/fixed electronic devices and laptops thus leading to a heightened demand for new services and improved speech quality. Dictaphones used for dictations usually have one microphone. LÄS MER

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

5. 9. Acoustic Beamforming : Design and Development of Steered Response Power With Phase Transformation (SRP-PHAT).

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Ajoy Kumar Dey; Susmita Saha; [2011]
   Nyckelord :Acoustic Beamforming; SRP-PHAT; Sound Source Localization; Source Position; Microphone Array algorithm;

   Sammanfattning : Acoustic Sound Source localization using signal processing is required in order to estimate the direction from where a particular acoustic source signal is coming and it is also important in order to find a soluation for hands free communication. Video conferencing, hand free communications are different applications requiring acoustic sound source localization. LÄS MER

7. 10. Acoustic speech source localization in a constrained search space

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Samson Mwela John; [2010]
   Nyckelord :Acoustic; constrained; localization; Microphone array; SRP-PHAT;

   Sammanfattning : Localization of an acoustic source by using algorithms that estimate the direction from which the acoustic signal is coming from, helps to address a long time hands-free communications challenge. Applications such as video conferencing, robot processing, hands-free communications, etc require a robust algorithm that accurately locates the Direction of Arrival of incoming wave-fronts with high precision.
