    Sammanfattning : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. LÄS MER

  4. 13. That voice sounds familiar : factors in speaker recognition

    Författare :Erik J. Eriksson; Kirk P. H. Sullivan; Christopher Darwin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; accent; emotions; hearing; spectral moments; formant transitions; dialect; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : Humans have the ability to recognize other humans by voice alone. This is important both socially and for the robustness of speech perception. This Thesis contains a set of eight studies that investigates how different factors impact on speaker recognition and how these factors can help explain how listeners perceive and evaluate speaker identity.
