The aim of this discussion paper is twofold: on the one hand it is intended to present the rather unstructured situation with respect to the terminology of i) laughter types, ii) laughter segments and iii) further interactional vocalisations. On the other hand these three areas shall be discussed with concrete examples taken from a spontaneous dialogue corpus. An exchange of ideas about the pros and cons of the various names and approaches of segmentation can help to establish a more standardised use of terms to overcome the slightly chaotic situation of labelling elements of interactional vocalisations.
