  1. 11. 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. 12. Speech perception, phonological sensitivity, and articulation in early vocabulary development

    Författare :Iris-Corinna Schwarz; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; speech perception; phonological representation; language acquisition; early vocabulary development; lexical restructuring; Children s language; Barnspråk;

    Sammanfattning : Speech perception, articulation, and word learning are three major tiers of language development in young children, integrating perceptual and productive language abilities. Infant speech perception precedes speech production and is the basis for native language learning. LÄS MER

  4. 13. Found speech and humans in the loop : Ways to gain insight into large quantities of speech

    Författare :Per Fallgren; Jens Edlund; Fred Cummins; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Found data; found speech; human-in-the-loop; sound browsing; dimensionality reduction; visualization; crowdsourcing; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : Found data - data used for something other than the purpose for which it was originally collected - holds great value in many regards. It typically reflects high ecological validity, a strong cultural worth, and there are significant quantities at hand. However, it is noisy, hard to search through, and its contents are often largely unknown. LÄS MER

  5. 14. Speech masking speech in everyday communication : The role of inhibitory control and working memory capacity

    Författare :Victoria Stenbäck; Birgitta Larsby; Björn Lyxell; Mathias Hällgren; Jonas Brännström; Linköpings universitet; []

    Sammanfattning : Age affects hearing and cognitive abilities. Older people, with and without hearing impairment (HI), exhibit difficulties in hearing speech in noise. LÄS MER

  7. 15. Quantization, Perception and Speech Coding

    Författare :Fredrik Nordén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is about compression of speech signals, a research area known as speech coding. The aim of a speech coder is to provide efficient digital representations of speech signals, required in digital transmission and storage systems. Contemporary speech coding algorithms typically separate the speech signal into sets of parameters. LÄS MER
