3. 2. On Speech-to-Text Alignment, Phonetic Labeling, and Recursive Signal Processing

   Författare :Åke Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phonetic labeling; recursive algorithms; adaptive algorithms; speech-to-text alignment; dynamic programming; time-varying systems; subspace tracking; time-alignment; parameter estimation; time-warping;

   Sammanfattning : Speech data-bases are an important issue in the study of speech communication. In particular, time-aligned and phonetically labeled speech data-bases are useful during the design of applications such as speech recognizers. The time-alignment and labeling of the speech data is traditionally done manually. LÄS MER

   Författare :Minh Truong; Elena Gutierrez-Farewik; Ruoli Wang; Emelie Butler Forslund; Åke Seiger; Peter Christian Raffalt; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gait analysis; pathological gait; biomechanics; health informatics; metabolic cost; unsupervised learning; nonparametric regression; shapley addictive explanations; gånganalys; funktionsnedsättning; gångpatologi; energiförbrukning; maskininlärning; hälsoinformatik; biomekanik; AI; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Spinal cord injury, whether traumatic or nontraumatic, can partially or completely damage sensorimotor pathways between the brain and the body, leading to heterogeneous gait abnormalities. Mobility impairments also depend on other factors such as age, weight, time since injury, pain, and walking aids used. LÄS MER

5. 4. On Prosodic Modification of Speech

   Författare :Barbara Resch; Bastiaan Kleijn; Thomas Eriksson; KTH; []
   Nyckelord :;

   Sammanfattning : Prosodic modification has become of major theoretical and practical interest in the field of speech processing research over the last decades. Algorithms for time and pitch scaling are used both for speech modification and for speech synthesis. LÄS MER

7. 5. Sensor-based knowledge- and data-driven methods : A case of Parkinson’s disease motor symptoms quantification

   Författare :Somayeh Aghanavesi; Mark Dougherty; Mobyen Uddin Ahmed; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Parkinson’s disease; motion sensors; motor symptoms; smartphone; microdata; multivariate analysis; data-driven; knowledge-driven; support vector machine stepwise regression; predictive models; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : The overall aim of this thesis was to develop and evaluate new knowledge- and data-driven methods for supporting treatment and providing information for better assessment of Parkinson’s disease (PD).PD is complex and progressive. There is a large amount of inter- and intravariability in motor symptoms of patients with PD (PwPD). LÄS MER
