  1. 1. Design and Evaluation of a Real-Time Sensor Monitor System on Raspberry Pi using Xenomai

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :David Rene Gonzalez; [2019]
    Nyckelord :;

    Sammanfattning : A real-time system computes information before a deadline in a deterministic fashion.Xenomai is a real-time framework to port real-time industrial applications to Linux. Ithas a dual-kernel architecture, with one kernel dedicated to handling real-time tasksexclusively. This co-kernel operates along with the Linux kernel in the same memoryspace. LÄS MER

  3. 2. MOBILE PHONE ACOUSTICS : PERFORMANCE EVALUATION OF SPECTRAL SUBTRACTION AND ELKO’S ALGORITHM USING SPEECH QUALITY METRICS

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sai Kiran Chittajallu; [2013]
    Nyckelord :Acoustics; PESQ; ELKOS; Spectral Subtraction; WOLA; Reverberation;

    Sammanfattning : In recent years a great deal of effort has been expended to develop methods that determine the quality of speech through the use of comparative algorithms. These methods are designed to calculate an index value of quality that correlates to a mean opinion score given by human subjects in evaluation sessions. LÄS MER

  4. 3. 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

  5. 4. Speech enhancement methods in hands-free communication with emphasis on Optimal SNIR Beamformer

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Harish Midathala; [2012]
    Nyckelord :signal to noise ratio; Beamforming; Reverberated and Anechoic; Speech intelligibility; Reverberation.;

    Sammanfattning : A basic speech enhancement can be achieved by the suppression of background noise and reverberation from the clean speech. The point to be noted is to achieve it with a low computational complexity. The aim is to estimate signal arriving optimally from the desired direction in the presence of reverberant-noisy speech signal. LÄS MER
