    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

    Abstract : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. READ MORE

  3. 3. The /k/s, the /t/s, and the inbetweens : Novel approaches to examining the perceptual consequences of misarticulated speech

    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; speech perception; speech disorders; speech synthesis; speech analysis; Tal- och musikkommunikation; Speech and Music Communication;

    Abstract : This thesis comprises investigations of the perceptual consequences of children’s misarticulated speech – as perceived by clinicians, by everyday listeners, and by the children themselves. By inviting methods from other areas to the study of speech disorders, this work demonstrates some successful cases of cross-fertilization. READ MORE

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

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

    Abstract : 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.
