Resumen:
In conversation, speakers have been shown to entrain, or become more
similar to each other, in various ways. We measure entrainment on
eight acoustic features extracted from the speech of subjects playing
a cooperative computer game and associate the degree of entrainment
with a number of manually-labeled social variables acquired using
Amazon Mechanical Turk, as well as objective measures of dialogue
success. We find that male-female pairs entrain on all features, while
male-male pairs entrain only on particular acoustic features
(intensity mean, intensity maximum and syllables per second). We further determine that entrainment
is more important to the perception of female-male social behavior
than it is for same-gender pairs, and it is more important to the
smoothness and flow of male-male dialogue than it is for female-female
or mixed-gender pairs. Finally, we find that entrainment is more pronounced when intensity or speaking rate is especially high or low.
