  1. 1. Automatic Speech Quality Assessment in Unified Communication : A Case Study

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Kevin Larsson Alm; [2019]
    Nyckelord :speech; voice; communication; qoe; quality of experience; unified communication; uc; speech quality assessment; speech quality; voice calls; gaussian mixture model; gmm; gaussian mixture regression; gmr; mel frequency cepstrum coefficients; mfcc; human feature cepstrum coefficients; hfcc; gammatone frequency cepstral coefficients; gfcc;

    Sammanfattning : Speech as a medium for communication has always been important in its ability to convey our ideas, personality and emotions. It is therefore not strange that Quality of Experience (QoE) becomes central to any business relying on voice communication. LÄS MER

  2. 2. A performance measurement of a Speaker Verification system based on a variance in data collection for Gaussian Mixture Model and Universal Background Model

    Magister-uppsats, Malmö universitet/Teknik och samhälle

    Författare :Zeid Bekli; William Ouda; [2018]
    Nyckelord :Speaker recognition; Speaker Verification; Speaker authentication; Speaker classification; Gaussian mixture model; Gaussian Mixture Model-Universal Background Model; Biometric System; Equal Error Rate; False Negative Rate; False Positive Rate; Mel Frequency Cepstrum Coefficients;

    Sammanfattning : Voice recognition has become a more focused and researched field in the last century, and new techniques to identify speech has been introduced. A part of voice recognition is speaker verification which is divided into Front-end and Back-end. LÄS MER

  3. 3. Musical Instrument Categorization using Spectral- and Cepstral Analysis

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Jakob Florén; Joel Torby; [2016]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : This thesis suggests and tests two methods for categorizing instruments in a musical signal. The first method involves spectral analysis and the magnitude spectrum, analysing the structure of pitches and overtones and how the amplitude of those changes over time. LÄS MER

  4. 4. Research and simulation on speech recognition by Matlab

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Linlin Pan; [2014]
    Nyckelord :speech recognition; algorithm; MFCC; GMM;

    Sammanfattning : With the development of multimedia technology, speech recognition technology has increasingly become a hotspot of research in recent years. It has a wide range of applications, which deals with recognizing the identity of the speakers that can be classified into speech identification and speech verification according to decision modes.
