  1. 1. The Virtual Language Teacher : Models and applications for language learning using embodied conversational agents

    Författare :Preben Wik; Björn Granström; Olov Engwall; Valerie Hazan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Language learning; embodied conversational agents; speech technology; computer assisted language learning; computer assisted pronunciation training; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : This thesis presents a framework for computer assisted language learning using a virtual language teacher. It is an attempt at creating, not only a new type of language learning software, but also a server-based application that collects large amounts of speech material for future research purposes.

  3. 2. Developing and evaluating co-speech gesture-synthesis models for embodied conversational agents

    Författare :Taras Kucherenko; Hedvig Kjellström; Gustav Eje Henter; Iolanda Leite; Jonas Beskow; Stefan Kopp; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human-agent interaction; gesture generation; social robotics; conversational agents; non-verbal behavior; deep learning; machine learning; Computer Science; Datalogi;

    Sammanfattning :  A  large part of our communication is non-verbal:   humans use non-verbal behaviors to express various aspects of our state or intent.  Embodied artificial agents, such as virtual avatars or robots, should also use non-verbal behavior for efficient and pleasant interaction.

  4. 3. Embodying Politeness in Persuasive Humanoid Agents for Small Group Scenarios

    Författare :Sahba Zojaji; Christopher Peters; Tony Belpaeme; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; politeness; persuasiveness; small free-standing conversational groups; embodiment; embodied conversational agents; humanoid robots; virtual reality; immersiveness; human-agent interaction; social norms; multimodal expressive communication; artighet; övertalningsförmåga; små fristående samtalsgrupper; förkroppsligande; förkroppsligade samtalsagenter; humanoida robotar; virtuell verklighet; uppslukande; interaktion mellan människa och agent; sociala normer; multimodal uttrycksfull kommunikation;

    Sammanfattning : In both physical and virtual environments, small group interactions significantly shape our social experiences. Understanding and replicating situated group interactions with virtual agents or physical robots pose possibilities and challenges. LÄS MER

  5. 4. Scalable Methods for Developing Interlocutor-aware Embodied Conversational Agents : Data Collection, Behavior Modeling, and Evaluation Methods

    Författare :Patrik Jonell; Jonas Beskow; Joakim Gustafsson; Gustav Eje Henter; Justine Cassell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-verbal behavior generation; interlocutor-aware; data collection; behavior modeling; evaluation methods; Tal- och musikkommunikation; Speech and Music Communication;

    Sammanfattning : This work presents several methods, tools, and experiments that contribute to the development of interlocutor-aware Embodied Conversational Agents (ECAs). Interlocutor-aware ECAs take the interlocutor's behavior into consideration when generating their own non-verbal behaviors. LÄS MER

  7. 5. EXPERIENCES OF SPEAKING WITH CONVERSATIONAL AI IN LANGUAGE EDUCATION

    Författare :Elin Ericsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Conversational artificial intelligence; Dialogue-based computer-assisted language learning; Educational experience; Embodied conversational agent; Student–conversational-agent interaction framework; Lower-secondary students; Speaking skills; Spoken dialogue system; Teachers;

    Sammanfattning : This thesis explores the application of digital tools in Swedish language education, specifically in relation to speaking skills. It focuses on dialogue- based, computer-assisted language learning, which enables students to practise and develop their speaking skills in a target language. LÄS MER
