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

    University dissertation from Christina Samuelsson, Högdalsgatan 17, 587 31 Linköping

    Author : Christina Samuelsson; [2004]
    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

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

    University dissertation from Stockholm : Signaler, sensorer och system

    Author : Harald Pobloth; Bastiaan Kleijn; Gernot Kubin; [2004]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Linguistics and Phonetics

    Author : Susanne Schötz; [2006]
    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
