2. 16. Impact of deep brain stimulation in the caudal zona incerta on voice tremor and speech in persons with essential tremor

   Author : Linda Sandström; Fredrik Karlsson; Patric Blomstedt; Lena Hartelius; Adam Vogel; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caudal zona incerta; deep brain stimulation; essential tremor; speech function; speech intelligibility; speech production; voice tremor;

   Abstract : Objectives: Deep brain stimulation (DBS) is a symptomatic treatment for people with essential tremor (ET) who have unsatisfactory tremor relief with pharmacological treatment alone. A common symptom of ET is voice tremor, but only about 50% of patients with voice tremor get a satisfactory result with DBS. READ MORE

4. 17. 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

5. 18. Towards conversational speech synthesis : Experiments with data quality, prosody modification, and non-verbal signals

   Author : Bajibabu Bollepalli; Joakim Gustafsson; Jonas Beskow; Matthew Aylett; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speech synthesis; MPEG compression; Voice Conversion; Artificial Neural Net- works; Laughter synthesis; HTS; Computer Science; Datalogi;

   Abstract : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. READ MORE

6. 19. 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.

7. 20. I tweet like I talk : Aspects of speech and writing on Twitter

   Author : Peter Wikström; Erica Sandlund; Solveig Granath; Andrea C. Schalley; Ruth Page; Karlstads universitet; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social media; Twitter; speech; writing; orality; literacy; CMC; remediation; English; Engelska;

   Abstract : This dissertation investigates linguistic and metalinguistic practices in everyday Twitter discourse in relation to aspects of speech and writing. The overarching aim is to investigate how the spoken–written interface is reconfigured in the digital writing spaces of social media. READ MORE
