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

    Författare :Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 22. Voice Imitation : A Phonetic Study of Perceptual Illusions and Acoustic Success

    Författare :Elisabeth Zetterholm; Allmän språkvetenskap; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 23. Assessment of assistive technology : outcomes, costs and quality

    Författare :Ursula Hass; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Technology assessment aims at providing information about costs and effects, in order to support decision making and resource allocation. The purpose of this thesis is to, through empirical studies on assistive technologies, investigate the contribution of various kinds of outcome measures, and provide knowledge about outcomes, costs and quality of services.

  5. 24. Counteracting Acoustic Disturbances in Human Speech Communication

    Författare :Nils Westerlund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Noise Reduction; Hearing Aids; Adaptive Feedback Control; Ear-Mic; Active Noise Control;

    Sammanfattning : A signal can be said to be any information bearing unit or action carrying a message from a sender to a receiver. This definition covers a vast number of human and non-human actions, ranging from flirtation to satellite communication. This thesis deals with increasing the quality of one of the most ubiquitous human-to-human signals: Speech. LÄS MER

  7. 25. Reading, spelling and silent speech: Exploring literacy in children with severe speech and physical impairment

    Författare :Maria Larsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; phonological awareness; reading; spelling; memory; speech impairment; cross-linguistic; cerebral palsy.;

    Sammanfattning : Most children with severe speech and physical impairment (SSPI) find it difficult to reach a functional level of literacy. This thesis aimed at exploring literacy in children with SSPI from two different linguistic environments, examining the importance of phonological awareness, memory abilities and characteristics of the spoken language.
