This is a collection of 19 short papers presented at the Laughter and Other Non-Verbal Vocalisations Workshop (Bielefeld, October 5, 2020). The conference brings together scientists from diverse research areas and provides an exchange forum for interdisciplinary discussions.
Non-verbal vocalisations play important roles in displaying social and affective behaviours and in controlling the flow of interaction in human-human and human-machine interactions. Laughs, sighs, filled pauses, and short utterances such as feedback responses are among non-verbal vocalisations that have been studied by various research fields. However, much is still unknown about the phonetic or visual characteristics of non-verbal vocalisations and their relations to intentions and perceived meanings in interaction. Furthermore, with the increased need for naturalness in human-machine interaction, it is worth exploring how laughter and other non-verbal vocalisations can be integrated in speech applications.
