Prosodic and multimodal markers
of humor in conversation 47
from Pickering et al. (2009) that are relevant to the present study. Using a sample
of ten speakers each performing two jokes, one provided to the participants and
one improvised by them,
we found that
– Punch lines were significantly lower in pitch than the set-up of the joke (we
confirmed this finding using semitone data rather than raw F0 measurements;
on average punch lines were 1.73 semitones lower than the setup).
– Punch lines were produced at slightly higher amplitude which was on av-
erage 0.2 dB higher in volume; however the difference was not statistically
significant.
– Punch lines were not preceded by significant pauses; in fact, 15 jokes (75% of
the texts) did not have a significant pause before the punch line.
– Speakers tended to deliver the punch line of the joke at a significantly slower
rate than the set-up in both types of jokes.
– 60% of jokes had either laughter
or smiling voice or both, in the punch line.
