   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speech; Speech disorders; Speech intelligibility; Speech perception; Computer linguistics; phonetic; Man-computer-interaction; Computational linguistics; Datorlingvistik;

   Abstract : This thesis studies disfluency in spontaneous Swedish speech, i.e., the occurrence of hesitation phenomena like eh, öh, truncated words, repetitions and repairs, mispronunciations, truncated words and so on. READ MORE

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

5. 3. Disruption of writing in noisy office environments

   Author : Marijke Keus van de Poll; Patrik Sörqvist; Stefan Wiens; Högskolan i Gävle; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; background speech; writing; speech intelligibility; Speech Transmission Index; masking; sound source location; working memory capacity; inattention; noise sensitivity; task interruptions; bakgrundsprat; skriva; taluppfattbarhet; Speech Transmission Index; maskering; ljudposition; arbetsminneskapacitet; uppmärksamhet; ljudkänslighet; uppgiftsavbrott; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

   Abstract : The overall aim of the four experimental studies included in this dissertation was to investigate the influence of background speech on writing performance. In Paper I, a manipulation of speech intelligibility of background speech, by using the Speech Transmission Index (STI), revealed disruptive effects at lower STI values (i.e. READ MORE

6. 4. Knowledge-based speech enhancement

   Author : Sriram Srinivasan; Bastiaan Kleijn; Rainer Martin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech enhancement; noise reduction; linear predictive coe±cients; autoregressive; codebooks; maximum-likelihood; Bayesian; nonstationary noise; blind source separation.; Telecommunication; Telekommunikation;

   Abstract : Speech is a fundamental means of human communication. In the last several decades, much effort has been devoted to the efficient transmission and storage of speech signals. With advances in technology making mobile communication ubiquitous, communications anywhere has become a reality. READ MORE

7. 5. Cognition in Hearing Aid Users : Memory for Everyday Speech

   Author : Hoi Ning Elaine Ng; Jerker Rönnberg; Mary Rudner; Thomas Lunner; Kevin Munro; Linköpings universitet; []
   Keywords : Hearing aid; working memory; free recall; noise reduction; speech recognition; Hörapparat; arbetsminne; återgivning; brusreducering; taluppfattning;

   Abstract : The thesis investigated the importance of cognition for speech understanding in experienced and new hearing aid users. The aims were 1) to develop a cognitive test (Sentence-final Word Identification and Recall, or SWIR test) to measure the effects of a noise reduction algorithm on processing of highly intelligible speech (everyday sentences); 2) to investigate, using the SWIR test, whether hearing aid signal processing would affect memory for heard speech in experienced hearing aid users; 3) to test whether the effects of signal processing on the ability to recall speech would interact with background noise and individual differences in working memory capacity; 4) to explore the potential clinical application of the SWIR test; and 5) to examine the relationship between cognition and speech recognition in noise in new users over the first six months of hearing aid use.
