  1. 1. Developing Multimodal Spoken Dialogue Systems : Empirical Studies of Spoken Human–Computer Interaction

    Författare :Joakim Gustafson; KTH; []
    Nyckelord :Spoken dialogue system; multimodal; speech; GUI; animated agents; embodied conversational characters; talking heads; empirical user studies; speech corpora; system evaluation; system development; Wizard of Oz simulations; system architecture; linguis; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents work done during the last ten years on developing five multimodal spoken dialogue systems, and the empirical user studies that have been conducted with them. The dialogue systems have been multimodal, giving information both verbally with animated talking characters and graphically on maps and in text tables. LÄS MER

  2. 2. Language Modelling and Error Handling in Spoken Dialogue Systems

    Författare :Genevieve Gorrell; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Language Modelling; Spoken Dialogue Systems; Error Handling; Computer science; Datavetenskap;

    Sammanfattning : Language modelling for speech recognition is an area of research currently divided between two main approaches: stochastic and grammar-based approaches are each being differently preferred for their respective strengths and weaknesses. At the same time, dialogue systems researchers are becoming aware of the potential value of handling recognition failures better to improve the user experience. LÄS MER

  3. 3. Error Handling in Spoken Dialogue Systems : Managing Uncertainty, Grounding and Miscommunication

    Författare :Gabriel Skantze; Rolf Carlson; Alexander Rudnicky; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; speech communications; linguistics; Language technology; Språkteknologi;

    Sammanfattning : Due to the large variability in the speech signal, the speech recognition process constitutes the major source of errors in most spoken dialogue systems. A spoken dialogue system can never know for certain what the user is saying, it can only make hypotheses. LÄS MER

  4. 4. Dialogue processes in computer-mediated communication : a study of letters in the COM system

    Författare :Kerstin Severinson Eklundh; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dialogue; Discourse analysis; Feedback; Question strategies; Written communication; Computer-mediated communication; Message systems; COM system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This thesis concerns the basic communicative potentials of a new communications medium: computer-based communication systems. The computer medium has properties which makes it possible to carry out an interactive dialogue, although messages are written and there is a delay between successive contributions. LÄS MER

  5. 5. Data-driven Methods for Spoken Dialogue Systems : Applications in Language Understanding, Turn-taking, Error Detection, and Knowledge Acquisition

    Författare :Raveesh Meena; Gabriel Skantze; Joakim Gustafson; Helen Hastie; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Language Understanding; Turn-taking; Error Detection; Knowledge Acquisition; Crowdsourcing; semantisk tolkning talspråk; turtagning i dialogsystem; fel och missförstånd; crowdsourcing; dialogsystem; Speech and Music Communication; Tal- och musikkommunikation;

    Sammanfattning : Spoken dialogue systems are application interfaces that enable humans to interact with computers using spoken natural language. A major challenge for these systems is dealing with the ubiquity of variability—in user behavior, in the performance of the various speech and language processing sub-components, and in the dynamics of the task domain.
