  1. 1. That voice sounds familiar factors in speaker recognition

    Detta är en avhandling från Umeå : Filosofi och lingvistik

    Författare :Erik J. Eriksson; Kirk P. H. Sullivan; Christopher Darwin; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; accent; emotions; hearing; spectral moments; formant transitions; dialect; TECHNOLOGY Information technology Computer science Cognitive science; TEKNIKVETENSKAP Informationsteknik Datavetenskap 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.

  2. 2. Automatic speaker verification on site and by telephone: methods, applications and assessment

    Detta är en avhandling från Stockholm : KTH

    Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Information and language technology; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informations- och språkteknologi;

    Sammanfattning : Speaker verification is the biometric task of authenticating a claimed identity by means of analyzing a spoken sample of the claimant's voice. The present thesis deals with various topics related to automatic speaker verification (ASV) in the context of its commercial applications, characterized by co-operative users, user-friendly interfaces, and requirements for small amounts of enrollment and test data.

  3. 3. Perception, Analysis and Synthesis of Speaker Age

    Detta är en avhandling från Linguistics and Phonetics

    Författare :Susanne Schötz; [2006]
    Nyckelord :HUMANIORA; HUMANITIES; phonology; perceptual cues; speaker age; automatic speaker recognition; acoustic analysis; acoustic correlates; data-driven; Phonetics; formant synthesis; Fonetik; fonologi; Technological sciences; Teknik;

    Sammanfattning : Speaker age is an important paralinguistic feature in speech which has to be considered in the study of phonetic variation. Knowledge about this feature may be used to improve speech technology applications, e.g. automatic speech recognition and speech synthesis. LÄS MER

  4. 4. Accounting for Individual Speaker Properties in Automatic Speech Recognition

    Detta är en avhandling från Linguistics and Phonetics

    Författare :Daniel Elenius; Björn Granström; Mats Blomberg; Torjbjörn Svendsen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MAP; MLLR; VTLN; speaker characteristics; dynamic modeling; child; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Information and language technology; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informations- och språkteknologi;

    Sammanfattning : In this work, speaker characteristic modeling has been applied in the fields of automatic speech recognition (ASR) and automatic speaker verification (ASV). In ASR, a key problem is that acoustic mismatch between training and test conditions degrade classification per- formance. LÄS MER
