This paper describes a new interface for a barge-in free spoken dialogue system combining an adaptive sound field control and a microphone array. In order to actualize robustness against the change of transfer functions due to the various interferences, the barge-in free spoken dialogue system which uses sound field control and a microphone array has been proposed by one of the authors. However...

We propose an argument-based foundation for dialogue games capable of modelling protocols for exchange of arguments in dialogues to prove or disprove propositions. We introduce structure into dialogue states by modelling them as dialogue trees coupled with appropriate annotation mechanisms. We model dialogue locutions as transformations between dialogue states. Viewing dialogues as proofs, we s...

A barge-in free spoken dialogue interface using sound field control and microphone array is proposed. In the conventional spoken dialogue system using an acoustic echo canceller, it is indispensable to estimate a room transfer function, especially when the transfer function is changed by various interferences. However, the estimation is difficult when the user and the system speak simultaneousl...

This paper provides a concise introduction to the MAgtALO system. This prototype software environment provides a mechanism enabling users to engage in online debate using naturalistic dialogue underpinned by sound argumentation theory. MAgtALO is used to demonstrate how dialogue protocols can be applied to support flexible intuitive interaction within complex and contentious problem domains.

This paper describes the collection and processing of a pilot speech corpus annotated in dialogue acts. The Mandarin Topic-oriented Conversational Corpus (MTCC) consists of annotated transcripts and sound files of conversations between two familiar persons. Particular features of spoken Mandarin, such as discourse particles and paralinguistic sounds, are taken into account in the orthographical...

For over five decades after the introduction of ‘talking movies’, the soundtracks of films were recorded in various types of analogue forms, such as variable-area optical film, variable-density optical film and magnetically-coated film. From the 1920s to the early 1970s, the background noise (hiss) inherent in the recording processes limited the level to which the sound could be amplified befor...
