Prosodic and multimodal markers
of humor in conversation 49
4.2
Volume
The present study is consistent with the result in Pickering et al. (2009): humor-
ous turns are produced on average 0.99 dB higher than serious turns (0.2 dB in
Pickering et al. 2009). This difference, as it was in Pickering et al. (2009), is insig-
nificant. We conclude that canned jokes and conversational jokes do not differ in
terms of volume marking of the humor. Like for pitch, we checked if humor may
differ in volume from the preceding turn, but we found no significant difference
in volume, with the humor being one decibel softer than the preceding turn, on
average (Table 5, Decibel measures).
4.3
Speech rate
As we saw, the present study found no significant difference in the speech rate of
humorous and serious turns. This is at variance with the results of Pickering et
al. (2009) where we have found that punch lines were delivered at a significantly
slower rate than the surrounding text. We return to this datum below.

Comparison of conversational humor vs. canned humor
An issue of importance in the pragmatics of humor has been the differences be-
tween conversational/discursive humor and narrative/canned humor. In this con-
text, we are interested in the prosodic
differences between the two, if any.
5.1
Speech rate
We noted above that the results of the present study failed to duplicate the signifi-
cantly lower speech rate of punch lines, found in Pickering et al. (2009). We found
instead no significant difference between serious and humorous turns’
speech
rate. However, we note that the narrative punch lines were delivered at the slowest
speech rate of all the humorous events (0.165 on average; see Table 2). Conversely,
irony and serious turns are essentially delivered at the same speech rate (0.265 and
0.27, respectively, see Table 2). Hence, we hypothesize that there may be a correla-
tion between narrative punch lines and lower speech rate, absent in irony and jab
lines. This may be then a difference between narrative and non-narrative humor
delivery.
