This case study extends the findings of Pickering et al. 2009 to the domain of conversational humor. It finds that, as was the case in humorous narratives, conversational humor is not marked by higher pitch or volume, increased speech rate, or significant pauses. Unlike narrative humor, conversational humor is not produced at a lower pitch and slower rate than non-humorous parts of the text. It is argued that smiling and laughter tend to occur with humor.
