  1. 16. Measuring Speech Quality of Laptop Microphone System using PESQ

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Praveen Lingapuram; [2012]
    Keywords : PESQ; wiener beamformer; spectral subtraction;

    Abstract : Signal compression algorithms are required in speech processing system to support the limited bandwidth requirements. And while compressing the signal, speech quality must not be degraded and modern speech methods makes use of perceptual information present in the signal to distinguish which part of the signal needs to be sent and which needs to be discarded.

  3. 17. Speech Intelligibility Measurement on the basis of ITU-T Recommendation P.863

    University essay from Laboratoriet för intelligenta system

    Author : SWATANTRA GHIMIRE; [2012]
    Keywords : Speech Intelligibility; POLQA;

    Abstract : Objective speech intelligibility measurement techniques like AI (Articulation Index) and AI based STI (Speech Transmission Index) fail to assess speech intelligibility in modern telecommunication networks that use several non-linear processing for enhancing speech. Moreover, these techniques do not allow prediction of single individual CVC (Consonant Vowel Consonant) word intelligibility scores. READ MORE

  4. 18. An Array of First Order Differential Microphone Strategies for Enhancement of Speech Signals

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Naresh Reddy NagiReddy; Arun Kumar Korva; [2012]
    Keywords : speech enhancement; beamforming; microphone array; elko algorithm; wiener beamformer; differential microphone ;

    Abstract : The quality and intelligibility of speech is degraded with the presence of background noise in the speech signal, which affects the listeners ability to understand the speech clearly. Speech enhancement is the process with which the background noise can be suppressed to improve the quality and intelligibility of the speech signal. READ MORE

  5. 19. Enhancement of Speech Intelligibility using Beamforming Techniques

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : LEELA KRISHNA GUDUPUDI; [2012]
    Keywords : Beamforming; Speech Enhancement; Microphone Arrays; PESQ; Delay-and-Sum;

    Abstract : Speech enhancement is a process of enhancing the intelligibility or quality of speech using various audio processing algorithms. The concept of speech enhancement is the most important field for many applications such as teleconferencing systems, speech recognition, VoIP, mobile phones, hearing aids, etc. [1]. READ MORE

  6. 20. Determining multimediastreaming content

    University essay from Institutionen för fysik

    Author : Richard Tano; [2011]
    Keywords : multimedia streams; video streams; video content; coding complexity; parametric models; QoS; MOS; ITU-T; P.NAMS; regression; frequent patterns;

    Abstract : This Master Thesis report was written by Umeå University Engineering Physics student Richard Tano during his thesis work at Ericsson Luleå. Monitoring network quality is of utmost importance to network providers. This can be done with models evaluating QoS (Quality of Service) and conforming to ITU-T Recommendations. READ MORE
