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

    Author : Shahram Moradi; Jerker Rönnberg; Björn Lidestam; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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). READ MORE

  4. 2. Lost in Translation : Speech recognition and memory processes in native and non-native language perception

    Author : Lisa Kilman; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Speech perception; perceived disturbance; native; non-native; working memory; language proficiency; episodic long-term memory; Taluppfattning; upplevd störning; modersmål; ett andra språk; arbetsminne; språkfärdigheter; episodiskt långtids-minne;

    Abstract : This thesis employed an integrated approach and investigated intra- and inter-individual differences relevant for normally hearing (NH) and hearing-impaired (HI) adults in native (Swedish) and non-native (English) languages in adverse listening conditions. The integrated approach encompassed the role of cognition as a focal point of interest as well as perceptualauditory and linguistic factors. READ MORE

  5. 3. Speech masking speech in everyday communication : The role of inhibitory control and working memory capacity

    Author : Victoria Stenbäck; Birgitta Larsby; Björn Lyxell; Mathias Hällgren; Jonas Brännström; Linköpings universitet; []

    Abstract : Age affects hearing and cognitive abilities. Older people, with and without hearing impairment (HI), exhibit difficulties in hearing speech in noise. READ MORE

  6. 4. Effects of environmental acoustic factors, individual differences and musical training on speech perception in simulated classrooms

    Author : Douglas MacCutcheon; Robert Ljung; Daniel Västfjäll; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; speech in noise; cognition; perception; musical training; spatial listening; virtual classroom environment; bakgrundsljud; kognition; taluppfattning; musikalisk träning; rumsligt lyssnande; virtuella klassrumsmiljöer; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Formal learning takes place primarily through speech perception in classroom environments and is therefore dependent on the listener’s ability to cope with a number of acoustic factors that interfere with the speech signal. As classrooms are inclusive spaces accommodating learners with a broad range of abilities and backgrounds, this research investigated some of the ways in which individual differences in supporting cognitive skills are related to speech perception outcomes in various challenging acoustic environments.

  7. 5. Hearing and cognition in speech comprehension. Methods and applications

    Author : Mathias Hällgren; Stig Arlinger; Birgitta Larsby; Arne Leijon; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; physiology; cognition; cognition disorders; dichotic listening tests; hearing loss; sensorineural; neuropsychological tests; speech perception; Audiology; Audiologi;

    Abstract : Central auditory processing is complex and can not be evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests and cognitive tests that tax functions important for speech processing. READ MORE
