   Sammanfattning : This thesis presents four experimental studies, carried out at the Phonetic laboratory, Stockholm University, on infants’ ability to establish auditory-visual sound-meaning associations as a precursor of early word acquisition. Study I reports on the effect of linguistic variance on infants’ ability (3- to 20-months) to establish sound-meaning associations. LÄS MER

3. 17. Acoustic Properties as Predictors of Perceptual Responses : a Study of Swedish Voiced Stops

   Författare :Diana Krull; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : 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.

4. 18. Effects of peripheral auditory adaptation on the discrimination of speech sounds

   Författare :Francisco Lacerda; Hartmut Traunmüller; Olle Engstrand; Björn Lindblom; Louis Pols; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Adaptation; discrimination; categorical perception; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This study investigates perceptual effects of discharge rate adaptation in the auditory-nerve fibers. Discrimination tests showed that brief synthetic stimuli with stationary formants and periodic source were better discriminated when they had an abrupt as opposed to a gradual onset (non-adapted vs adapted condition).

5. 19. En perceptuell och akustisk studie av svenskans koronaler i ett dialektperspektiv

   Författare :Peder Livijn; Anders Eriksson; Olle Engstrand; Frank Kügler; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Swedish; Dialect; Typology; Perceptual discrimination; Acoustical measurements; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : The purpose of this dissertation is to contribute to a typology of the Swedish language as it was spoken in the entire Swedish speaking area around the year 2000. Specifically, the plan is to base this typology solely on different pronunciations of the four coronal consonants /t, d, n/ and /l/. LÄS MER

7. 20. Phonetic Imitation, Accent, and the Learner

   Författare :Duncan Markham; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; sociolinguistics; talent; language acquisition; phonetics; Linguistics; Lingvistik;

   Sammanfattning : This work is concerned with the acquisition of the phonetic characteristics of languages and dialects, and with the issue of learner talent or individual achievement in learning second languages. Following a survey of the literature on language learning limits, it is argued that the concentration on group trends in most of the existing literature, whilst convenient, serves more to obscure the reasons for the difficulties experienced by most non-child language learners than to explain them.
