This study aims to test whether filled pauses (FPs) may highlight discourse structure. This question is tackled from the perspectives of both the speaker and the listener. More specifically , it is first investigated whether FPs are more typical in the vicinity of major discourse boundaries. Secondly, FPs are analyzed acoustically, to check whether those(More)
Speakers may use pitch accents as pointers to new information, or as signals of a contrast relation between the accented item and a limited set of alternatives. There is no consensus in the literature whether a separately identiiable contrastive accent exists. Some studies report that contrastive accents are more emphatic than newness accents and have a(More)
This paper first describes the aims of the prosodic annotation for (part of) the Spoken Dutch Corpus (Corpus Gesproken Nederlands, CGN), and the procedures that are currently being developed to produce the annotation. It further reports on a pilot study that was run to estimate the costs and the attainable quality (in terms of inter-transcriber consistency)(More)
From a discourse perspective, utterances may vary in at least two important respects: (i) they can occupy a different hierarchical position in a larger-scale information unit and (ii) they can represent different types of speech acts. Spoken language systems will improve if they adequately take into account both discourse segmentation and utterance purpose.(More)
Given the state of the art of current language and speech technology , errors are unavoidable in present-day spoken dialogue systems. Therefore, one of the main concerns in dialogue design is how to decide whether or not the system has understood the user correctly. In human-human communication, dialogue participants are continuously sending and receiving(More)
This paper describes two experiments on the role of audiovisual prosody for signalling and detecting meta-cognitive information in question answering. The Wrst study consists of an experiment, in which participants are asked factual questions in a conversational setting, while they are being Wlmed. Statistical analyses bring to light that the speakers'(More)
In human-human communication, dialogue participants are continuously sending and receiving signals on the status of the information being exchanged. We claim that if spoken dialogue systems were able to detect such cues and change their strategy accordingly, the interaction between user and system would improve. Therefore, the goals of the present study are(More)
