  3. 2. Semantic Framing of Speech : Emotional and Topical Cues in Perception of Poorly Specified Speech

    Författare :Björn Lidestam; Björn Lyxell; Staffan Hygge; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech perception; speechreading; facial expressions; priming; phonemes; semantics; lipreading; auditory perception; cognition; paralinguistics; emotional content; Läppavläsning; Psychology; Psykologi;

    Sammanfattning : The general aim of this thesis was to test the effects of paralinguistic (emotional) and prior contextual (topical) cues on perception of poorly specified visual, auditory, and audiovisual speech. The specific purposes were to (1) examine if facially displayed emotions can facilitate speechreading performance; (2) to study the mechanism for such facilitation; (3) to map information-processing factors that are involved in processing of poorly specified speech; and (4) to present a comprehensive conceptual framework for speech perception, with specification of the signal being considered.

  5. 4. Time is of the essence in speech perception! : Get it fast, or think about it

    Författare :Shahram Moradi; Jerker Rönnberg; Björn Lidestam; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Noise; auditory speech perception; audiovisual speech perception; hearing aids; Buller; hörsel; auditiv talperception; audiovisuell talperception; hörhjälpmedel;

    Sammanfattning : The present thesis examined the extent to which background noise influences the isolation point (IP, the shortest time from the onset of speech stimulus required for correct identification of that speech stimulus) and accuracy in identification of different types of speech stimuli (consonants, words, and final words in high-predictable [HP] and low-predictable [LP] sentences). These speech stimuli were presented in different modalities of presentation (auditory, visual, and audiovisual) to young normal-hearing listeners (Papers 1, 2, and 5). LÄS MER
