This study investigated the comparative effects of audio-visually prompted collaborative dialogue on the listening comprehension development of symmetrical, asymmetrical, and asymmetrical teacher-fronted EFL learner groups. Besides, it explored the attitude of the participants of the groups concerning the effectiveness of collaborative dialogue for their listening comprehension improvement. The...

This paper describes and compares two methods for simulating user behaviour in spoken dialogue systems. User simulations are important for automatic dialogue strategy learning and the evaluation of competing strategies. Our methods are designed for use with “Information State Update” (ISU)-based dialogue systems. The first method is based on supervised learning using linear feature combination ...

People with motor disabilities often face substantial challenges using interfaces designed for manual interaction. Although such obstacles might be partially alleviated by automatic speech recognition, these individuals may also have cooccurring speech-language challenges that result in high recognition error rates. In this paper, we investigate how augmenting speech applications with dialogue ...

studying the dialogue properties in rigveda and avesta indicates a type of dialogue called “philosophical dialogue” that is the synonym of “nonviolence”. according to the author, the initial root of forming the dramatic dialogue is based on philosophical dialogue, i.e. a type of fluidity and flow of meaning between two sides of the relation and by such relation it will be made a new concept. th...

Philosophical dialogue games have been used widely as models for protocols in multi-agent systems to improve flexibility, expressiveness, robustness and efficiency. However, many dialogue games are effectively based on propositional logic, which is not always sufficiently expressive for artificial reasoning. In particular they do not allow for a strong connection between computational models of...

Page 2 of 215 Abstract Embodied Conversational Agents (ECA) seek to provide a more natural means of interaction for a user through conversation. ECA build on the dialogue abilities of spoken dialogue systems with the provision of a physical or virtual avatar. The rationale for this Thesis is that an ECA should be able to support a form of conversation capable of understanding both the content a...

that users immediately start to go beyond the limits of the system directed dialogue structure and utilizing the built-in shortcuts. An even more pronounced effect of user habituation can be expected when users are exposed to a larger number of dialogues.Speech recognition error rates for digit strings and word spotting were found to be 16% on average. This seemed sufficient to ensure user acce...

A Spoken Dialogue System provide is a computer system able to converse with human with human voice. Dialogue Manager is a component of SDS that manages state of dialogue and dialogue strategy. This report presents the literature survey based on DM. The papers are based on various components of DM. The components of DM are dialogue representation, belief state representation, policy optimization...
