Conversational agent is a system that provides user with proper information and maintains the context of dialogue based on natural language. When experts design the network for conversational agent of a domain, the network is usually very complicated and is hard to be understood. So the simplification of network by separating variables in the domain is helpful to design the conversational agent...

Gaze is instrumental in coordinating face-to-face social interactions. But little is known about gaze use when social interactions co-occur with other joint activities. We investigated the case of walking while talking. We assessed how gaze gets allocated among various targets in mobile conversations, whether allocation of gaze to other targets affects conversational coordination, and whether r...

This paper presents our recent work on language identi-cation research using conversational speech (the LDC Conversational Telephone Speech Database). The base-line system used in this study was developed recently ((4, 5]). It is based on language-dependent phone recognition and phonotactic constraints. The system was trained using monologue data and obtained an error rate of around 9% on a com...

Automated analyses of full-day recordings were used to determine whether young children who are hard-of-hearing (HH) received similar levels of exposure to adult words and conversational interactions as age-matched peers with normal-hearing (NH). Differences in adult input between children in this study and in a normative database were considered. Finally, factors were examined that may have co...

The activity of speaking is conducted spontaneously and there is not much time devoted to preplanning and arranging the utterances the speaker intends to deliver. Briefly defined, gambits and routines refer to the words and phrases that facilitate the flow of conversations. As such, one way to help learners acquire oral proficiency is to teach gambits that support the social skills emphasized. ...

This paper introduces Paul Grice’s notion of conversational implicature. The basic ideas — the cooperative principle, the maxims of conversation, and the contrast between implicature and presupposition — make it clear that conversational implicature is a highly contextualized form of language use that has a lot in common with non-linguistic behavior. But what exactly is its role? We invite the ...

Humans use humour to ease communication problems in human-human interaction and in a similar way humour can be used to solve communication problems that arise with humancomputer interaction. We discuss the role of embodied conversational agents in human-computer interaction and we have observations on the generation of humorous acts and on the appropriateness of displaying them by embodied conv...

We propose the application of ubiquitous sensor technology to analyze dynamic structure transitions and the exchange of non-verbal information in multi-party human-to-human conversational interactions in open situations. We present an analysis of conversational interactions that took place in an open interaction space of poster presentation sessions and were collected as an Interaction Corpus. ...

The study examined the relationship between perinatal stress and decreased right handedness and decreased left cerebral dominance for speech with 215 children born prematurely, followed from birth, and tested at age 5. Results indicated that neither hand preference nor hand performance correlated with degree of perinatal stress and that eye preference was associated with perinatal stress though...
