2. 1. The language learning infant: Effects of speech input, vocal output, and feedback

   Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Prosody in Swedish Children with Language Impairment. Perceptual, Acoustic and Interactional Aspects

   Author : Christina Samuelsson; foniatri och audiologi Logopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen; audiology; Otorhinolaryngology; classification; acoustic evaluation; prosody; perceptual evaluations; language impairment;

   Abstract : The aim of this thesis was to explore prosodic problems in Swedish children with language impairment (LI). In the first study, 29 children with LI participated. They were assessed with an assessment procedure for prosody at the word, phrase and discourse levels, developed within this thesis. READ MORE

6. 4. Voice Imitation : A Phonetic Study of Perceptual Illusions and Acoustic Success

   Author : Elisabeth Zetterholm; Allmän språkvetenskap; []
   Keywords : HUMANIORA; HUMANITIES; impersonation; Voice and speech imitation; target voice; individual voice; pitch register; voice quality; prosody; semantic information; phonology; dialect; articulatory timing; speech style; Phonetics; Fonetik; fonologi;

   Abstract : This thesis is about voice imitations, more specifically impersonation. Questions are raised about the uniqueness of a person’s voice and speech behaviour and if it is possible to get close to another speaker’s voice and speech. Four main research questions are investigated in different studies. READ MORE

7. 5. Acoustic Properties as Predictors of Perceptual Responses : a Study of Swedish Voiced Stops

   Author : Diana Krull; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : In speech recognition algorithms and certain theories of speech perception the interpretation of the signal is based on " distance scores " for comparisons of the signal with stored references; in these theories, perception is seen as a product of stimulus and experience. The aim of the present thesis is to evaluate such distance measures by investigating the perceptual confusions of the Swedish voiced stops [b,d,q,g] in systematically varied fragments of vowel-consonantvowel stimuli providing 25 vowel contexts for each consonant.
