   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing impairment; normal hearing; age; speech-in-noise; working memory; inhibitory control; listening effort; Hörselnedsättning; normal hörsel; ålder; tal-i-brus; arbetsminne; inhibitionskontroll; lyssningansträngning;

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

4. 2. Probabilistic Modelling of Hearing : Speech Recognition and Optimal Audiometry

   Author : Svante Stadler; Arne Leijon; Stefan Stenfelt; KTH; []
   Keywords : auditory models; probabilistic modelling; speech modelling; human speech recognition; hearing aids; cochlear implants; psychoacoustics; diagnostic methods; optimal experiments; audiometry;

   Abstract : Hearing loss afflicts as many as 10\% of our population.Fortunately, technologies designed to alleviate the effects ofhearing loss are improving rapidly, including cochlear implantsand the increasing computing power of digital hearing aids. Thisthesis focuses on theoretically sound methods for improvinghearing aid technology. READ MORE

5. 3. Mining Speech Sounds : Machine Learning Methods for Automatic Speech Recognition and Analysis

   Author : Giampiero Salvi; Björn Granström; Torbjørn Svendsen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; speech; machine learning; data mining; signal processing; Computer science; Datavetenskap;

   Abstract : This thesis collects studies on machine learning methods applied to speech technology and speech research problems. The six research papers included in this thesis are organised in three main areas. The first group of studies were carried out within the European project Synface. READ MORE

6. 4. 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

7. 5. Neural and Cognitive Effects of Hearing Loss on Speech Processing

   Author : Eline Borch Petersen; Thomas Lunner; Stefan Stenfelt; Jonas Obleser; Edmund Lalor; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing loss; speech processing; electroencephalogram EEG; working memory; cognitive load; hearing aid; Hörselnedsättning; bearbetning av tal; elektroencefalogram EEG; arbetsminne; kognitiv belastning; hörapparat;

   Abstract : Understanding speech in the presence of noise can be difficult, especially when suffering from a hearing loss. This thesis examined behavioural and electrophysiological measures of speech processing with the aim of establishing how they were influenced by hearing loss (internal degradation) and listening condition (external degradation).
