2. 1. Semantic Framing of Speech : Emotional and Topical Cues in Perception of Poorly Specified Speech

   Author : Björn Lidestam; Björn Lyxell; Staffan Hygge; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech perception; speechreading; facial expressions; priming; phonemes; semantics; lipreading; auditory perception; cognition; paralinguistics; emotional content; Läppavläsning; Psychology; Psykologi;

   Abstract : The general aim of this thesis was to test the effects of paralinguistic (emotional) and prior contextual (topical) cues on perception of poorly specified visual, auditory, and audiovisual speech. The specific purposes were to (1) examine if facially displayed emotions can facilitate speechreading performance; (2) to study the mechanism for such facilitation; (3) to map information-processing factors that are involved in processing of poorly specified speech; and (4) to present a comprehensive conceptual framework for speech perception, with specification of the signal being considered.

4. 2. Perceptually motivated speech recognition and mispronunciation detection

   Author : Christos Koniaris; Olov Engwall; Martin Cooke; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; feature extraction; feature selection; auditory models; MFCCs; speech recognition; distortion measures; perturbation analysis; psychoacoustics; human perception; sensitivity matrix; pronunciation error detection; phoneme; second language; perceptual assessment;

   Abstract : This doctoral thesis is the result of a research effort performed in two fields of speech technology, i.e., speech recognition and mispronunciation detection. Although the two areas are clearly distinguishable, the proposed approaches share a common hypothesis based on psychoacoustic processing of speech signals. READ MORE

5. 3. From Acoustics to Articulation : Study of the acoustic-articulatory relationship along with methods to normalize and adapt to variations in production across different speakers

   Author : Gopal Ananthakrishnan; Olov Engwall; Gérard Bailly; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Acoustic-Articulatory relationship; speaker normalization;

   Abstract : The focus of this thesis is the relationship between the articulation ofspeech and the acoustics of produced speech. There are several problems thatare encountered in understanding this relationship, given the non-linearity,variance and non-uniqueness in the mapping, as well as the differences thatexist in the size and shape of the articulators, and consequently the acoustics,for different speakers.

6. 4. A Grammatical Description of Dameli

   Author : Emil Perder; Maria Koptjevskaja Tamm; Eva Lindström; Elena Bashir; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Dameli; Damiabaasha; grammatical description; descriptive grammar; grammar; Dardic; Hindu Kush languages; Indo-Aryan; dml; Linguistics; lingvistik;

   Abstract : This dissertation aims to provide a grammatical description of Dameli (ISO-639-3: dml), an Indo-Aryan language spoken by approximately 5 000 people in the Domel Valley in Chitral in the Khyber Pakhtunkhwa Province in the North-West of Pakistan. Dameli is a left-branching SOV language with considerable morphological complexity, particularly in the verb, and a complicated system of argument marking. READ MORE

7. 5. Sensory integration : success & failure

   Author : Tamas Jantvik; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Abstract : The convergence of sensory signals plays an important role in perception. Two cases of convergence are examined in this thesis by means of modelling; the case when the converging signals are congruent, which leads to combination and an enhancement of perception, and the case when they are incongruent.
