We propose an approach to reasoning about conversation protocols within the framework of a logic-based agent language. We show how to embed a theory of communicative actions in the framework of a modal logic of action and beliefs, to specify software agents that, situated in a multi-agent environment, can interact with one another by a speech act based communication mechanism. Agents have their...

Our goal is to collect a speech corpus for the purpose of studying intelligibility and acoustic differences between the conversational and clear speech styles. The ideal corpus has the following properties: (1) speech has been produced spontaneously as part of a communicative interaction, as opposed to having been read to an imagined interlocutor; (2) entire identical utterances, or large parts...


 Humans use language to give and receive information through various types of media, including audio visual media. In speech events, sentences show the intent purpose communicating. The words spoken by a speaker can indicate or speakers so that other people understand them more easily. every communication process, events acts occur. Speech are strongly influenced context situation. This i...

Gestures serve many roles, some expressive, some communicative, some for gesturer, some for listener. One role they serve is to express and communicate models. A gesture model is a sequence of related gestures that represent coherent aspects of a situation. Here, we select examples from our previous research of gesture models of spatial structure, spatial perspective, action, and narrative stru...

While speech synthesis research is now focussing on the generation of various speaking styles or emotions, very few studies have considered the possibility of including phonetic variations according to the communicative situation of the targeted speech (sports commentaries, TV news, etc.). This paper proposes a phonetic analysis of large French corpora to assess the influence exerted by three s...

Speech prosody, just like the segmental aspect of speech, conveys communicative meanings by encoding functional contrasts. The contrasts are realized through articulation, a biomechanical process with specific constraints. Prosodic phonology or any other theory of prosody therefore cannot be autonomous from either communicative functions or biophysical mechanisms. Successful modeling of speech ...

Although language is a key tool for communication in social interaction, most studies in the neuroscience of language have focused on language structures such as words and sentences. Here, the neural correlates of speech acts, that is, the actions performed by using language, were investigated with functional magnetic resonance imaging (fMRI). Participants were shown videos, in which the same c...

Cooperation is a complex task that necessarily involves communication and reasoning about others’ intentions and beliefs. Multi-agent communication languages aid designers of cooperating robots through standardized speech acts, sometimes including a formal semantics. But a more direct approach would be to have the robots plan both regular and communicative actions themselves. We show how two ro...

To confirm the language independency of a communicative prosody generation from input word impression vector, we synthesized communicative Mandarin speech using prosodic characteristics of communicative Japanese speech. The fundamental frequency and duration characteristics of oneword “n” utterances of Japanese were copied to Mandarin through input word attributes. From the subjective impressio...
