  1. 6. A "happy" approach to speechreading : the effects of facial expression, emotional content, and script information on speechreading performance

    Författare :Karina Johansson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The aim of the present thesis was to study if and how emotions in facial expressions affect speechreading performance. Speechreading is the understanding of spoken messages by watching the speaker's lips, taking facial expressions and situational cues into account. LÄS MER

  3. 7. Understanding virtual speakers

    Författare :Jens Nirme; The Educational Technology Group; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Verbal Comprehension; Multimodality; Audiovisual integration; Gesture; Educational Technology;

    Sammanfattning : This thesis addresses how verbal comprehension is affected by seeing the speaker and in particular when the speaker is an animated virtual speaker. Two people visually co-present – one talking and the other listening, trying to comprehend what is said – is a central and critical scenario whether one is interested in human cognition, communication or learning.

  4. 8. Expressiveness in virtual talking faces

    Författare :Gunilla Svanfeldt; Björn Granström; Francisco Lacerda; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Language technology; Språkteknologi;

    Sammanfattning : In this thesis, different aspects concerning how to make synthetic talking faces more expressive have been studied. How can we collect data for the studies, how is the lip articulation affected by expressive speech, can the recorded data be used interchangeably in different face models, can we use eye movements in the agent for communicative purposes? The work of this thesis includes studies of these questions and also an experiment using a talking head as a complement to a targeted audio device, in order to increase the intelligibility of the speech.

  5. 9. Methods for measurement of vocal fold vibration and viscoelasticity

    Författare :Hans Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :High-speed video imaging; kymography; acoustic analysis; vocal fold vibration; glottal edge; glottal area; laser; mucosal wave; triangulation; vocal fold; vocal fold length; vocal fold width; vocal fold strain; non-invasive; vocal fold scarring; air pulse stimulation;

    Sammanfattning : The overall aim of the thesis was to develop new methods for analysis of vocal fold vibrations and viscoelasticity and to test them in human subjects. In Study I the onset of vibration and irregular vocal fold vibration was examined with laryngoscopy using a high-speed camera at a frame rate of about 2000 images/sec. LÄS MER
