1. 6. Attitude to Speech and Communication in Individuals Born with Cleft Lip and Palate

   Författare :Christina Havstam; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cleft lip and palate; speech; communicative attitude; participation; satisfaction with speech; self-assessment; qualitative methods; grounded theory; interview; speech assessment;

   Sammanfattning : The overall aim of this thesis was to explore and describe how individuals who are born with a cleft lip and palate experience their communicative situation, how they perceive their speech and whether their views correlate with the results of speech assessments made by specialised speech-language pathologists (SLPs). Both quantitative and qualitative methods were used. LÄS MER

3. 7. Aerodynamic assessment of velopharyngeal function in speech

   Författare :Hans Dotevall; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Speech production measurements; speech aerodynamics; velopharyngeal function; nasal airflow; perceptual speech evaluation; hypernasality; cleft palate speech; sleep disordered breathing; snoring; sleep apnea;

   Sammanfattning : Velopharyngeal function in speech was assessed by aerodynamic techniques, which were developed and tested. Temporal and dynamic characteristics of the nasal airflow pattern during the velopharyngeal closing phase in speech were studied in different patient groups. Its validity in relation to listener's perceptual evaluation of speech was analyzed. LÄS MER

4. 8. Speech Signal Extraction : A Multichannel Approach

   Författare :Nedelko Grbic; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Blind signal separation; Echo control; Adaptive systems;

   Sammanfattning : In speech signal extraction the aim is to extract human speech in a physical environment by using microphones. In any real world environment there are many disturbance sources that cause unwanted sound pressure, which in turn may degrade the comprehension of the speech at the microphones. LÄS MER

   Sammanfattning : The aim of this dissertation is to contribute with knowledge about how speech communities are formed and maintained in Swedish preschools when minority language children participate. The dissertation is based on two empirical studies that are linked together by an ethnographical communication model. LÄS MER

7. 10. Entropy and Speech

   Författare :Mattias Nilsson; Bastian Kleijn; Sören Holdt Jensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech representation; energy concentration; entropy estimation; manifolds; Acoustics; Akustik;

   Sammanfattning : In this thesis, we study the representation of speech signals and the estimation of information-theoretical measures from observations containing features of the speech signal. The main body of the thesis consists of four research papers. Paper A presents a compact representation of the speech signal that facilitates perfect reconstruction. LÄS MER
