    Existing laughter annotations provided with several publicly available conversational speech corpora (both multiparty and dyadic conversations) were investigated and compared. We discuss the possibilities and limitations of these rather coarse and shallow laughter annotations. There are definition issues to be considered with respect to speech-laughs and the segmentation of laughs: what constitutes one laugh, and when does a laugh start and end? Despite these issues, some durational and voicing analyses can be performed. We found for all corpora considered that overlapping laughs are longer in duration and are generally more voiced than non-overlapping laughs. For a finer-grained acoustic analysis, we find that a manual re-labeling of the laughs adhering to a more standardized laughter annotations protocol would be optimal.
