    Sammanfattning : 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. LÄS MER

  3. 3. Perceptual and Squared Error Aspects in Speech and Audio Coding

    Detta är en avhandling från Stockholm : Signaler, sensorer och system

    Författare :Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; speech coding; audio coding; auditory models; perceptual distortion measures; squared error; Signalbehandling; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : In the process of quantization, speech and audio signals are changed. This thesis contains four papers concerned with comparing and minimizing different measures to quantify the changes introduced. Before quantization the signal can be transformed to another domain. Transforms related to the discrete Fourier transform allow for e. LÄS MER

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

    Detta är en avhandling från Stockholm : Signaler, sensorer och system

    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

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

    Detta är en avhandling från Linguistics and Phonetics

    Författare :Susanne Schötz; [2006]
    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
