  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. Acoustic Echo cancellation inside a Conference Room using Adaptive Algorithms

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Gannamaneni Geetha Chowdary; [2012]
    Keywords : Acoustic echo cancellation; Room modeling; Reverberation time; Signal to noise ratio; Echo return loss enhancement;

    Abstract : The whole dimension of communications has been changed by the rapid growth of technology. Today people are more interested in hands-free com-mucation, which makes use of loud speaker and high gain microphone, in place of the old modeled wired telephone. READ MORE

  4. 23. An Acoustic Echo Cancellation System based on Adaptive Algorithm

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Veeratej Garre; Sailesh Kumar Mannem; [2012]
    Keywords : AEC; Reverberation; Adaptive algorithms; Adaptive filters;

    Abstract : Adaptive filtering technique is one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry. Adaptive filtering technique is widely used in many applications, including echo cancellation, adaptive noise cancellation, adaptive beam forming and adaptive equalization. READ MORE

  5. 24. BLIND DECONVOLUTION AND ADAPTIVE ALGORITHMS FOR DE-REVERBERATION

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : SURYAVAMSI ATRESYA UPPALURU; [2012]
    Keywords : Adaptive algorithms; CMA; Reverberation; Reverberation index; Speech Distortion.;

    Abstract : De-reverberation of speech signals in a hands-free scenario by adaptive algorithms has been a research topic for several years now. However, it is still a challenging problem because of the nature of common room impulse response (RIR). READ MORE

  6. 25. Performance Analysis of Adaptive Algorithms based on different parameters Implemented for Acoustic Echo Cancellation in Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Swathi Kotte; [2011]
    Keywords : least mean square LMS Algorithm; Leaky Least mean square LLMS Algorithm; Normalized Least Mean Square NLMS Algorithm and Recursive Least Square RLS Algorithm ; additive white Gaussian noise ; Return Loss Enhancement ERLE ; signal to noise ratio;

    Abstract : Echo cancellation in voice communication is a process of removing the echo to improve the clarity, quality of the voice signals by suppressing the silence signal which prevents echoes during transmission through networks. There are two types of echo in voice communication: Hybrid echo cancellation and Acoustic echo cancellation. READ MORE
