1. 1. 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.

   Sammanfattning : This thesis has three main objectives. The first objective (A) includes Study I, which investigates the parameter fundamental frequency (F0) and its robustness in different acoustic contexts by using different measures. LÄS MER

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

   Författare :Håkan Melin; Björn Granström; Mats Blomberg; Josef Bigün; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speaker recognition; speaker verification; speech technology; biometrics; access control; speech corpus; variance estimation; Information and language technology; 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.

5. 4. Perception, Analysis and Synthesis of Speaker Age

   Författare :Susanne Schötz; Fonetik; []
   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
