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. The language learning infant: Effects of speech input, vocal output, and feedback

   Author : Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Abstract : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. READ MORE

5. 3. 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. 4. Computer-based speech therapy using visual feedback with focus on children with profound hearing impairments

   Author : Anne-Marie Öster; David House; James Mahshie; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech technology; hearing-imparment; speech therapy; visual feedback; second language learning; computer-based speech training; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : This thesis presents work in the area of computer-based speech therapy using different types of visual feedback to replace the auditory feedback channel. The study includes diagnostic assessment methods prior to therapy, type of therapy design, and type of visual feedback for different users during different stages of therapy for increasing the efficiency.

7. 5. Information state based speech recognition

   Author : Rebecca Jonson; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; dialogue systems; speech recognition; language modelling; dialogue move; dialogue context; ASR; higher level knowledge; linguistic knowledge; N-Best re-ranking; confidence scoring; confidence annotation; information state; ISU approach;

   Abstract : One of the pitfalls in spoken dialogue systems is the brittleness of automatic speech recognition (ASR). ASR systems often misrecognize user input and they are unreliable when it comes to judging their own performance. READ MORE
