Audiovisual prosody of uncertainty: An overview

Abstract

The goal of this work is to give an overview of research conducted in the field of
audiovisual prosody and uncertainty. We refer to previous studies investigating the
relevance of prosodic cues for both the production and perception of uncertainty
in natural conversation. Afterwards, we present our own experiments dealing with
the role of prosodic cues of uncertainty and also of context for pragmatic focus
interpretation. In a next step we discuss which role uncertainty plays for humanmachine
communication. In this context we summarise our own studies on the
modelling and perception of uncertainty in speech from an articulatory speech
synthesizer. We assume that speech synthesis systems with highly variable speech
can help to improve human-machine communication.
