Contextual Aspects of Prosody in Monologue Generation
نویسندگان
چکیده
This paper presents a theory concerning the dependence of intonational contours on discourse context, and expounds a framework for modeling contrastive stress, a phenomena whereby pitch accents are strategically placed based on their ability to discriminate among available discourse entities. The intonation theory, which is presented with respect to a model of discourse coherence inspired by Centering Theory [Grosz et al., 1986], is utilized to implement a monologue generation system which produces paragraph-length, prosodically appropriate, spoken descriptions of entities from a small knowledge base.

From corre...

Prosody and intonation convey important distinctions of “Information Structure”, marking portions of the utterance as standing in relations to the surrounding discourse such as “theme” and “rheme”, and marking relations of contrast between referring expressions and potential reference sets. The use of default intonation contours in standard “text-to-speech” applications can be quite successful,...
متن کاملIs it a Monologue, a Dialogue or a turn in a Dialogue?
The various approaches prevalent in argumentation theory take as their fundamental unit of analysis the concept of ‘an argument’. It is generally assumed that any unit of argument is inherently dialectical: Eemeren and Grootendorst (1992), for example, use the notion of an “implicit discussion”. It has recently been recognised, however, that there may be important differences between arguments ...
متن کاملData-oriented Monologue-to-Dialogue Generation
This short paper introduces an implemented and evaluated monolingual Text-to-Text generation system. The system takes monologue and transforms it to two-participant dialogue. After briefly motivating the task of monologue-to-dialogue generation, we describe the system and present an evaluation in terms of fluency and accuracy.
