In conversation, speakers have been shown to entrain, or become more similar to each other, in various ways. We measure entrain- ment on eight acoustic features extracted from the speech of subjects playing a cooperative computer game and associate the degree of en- trainment with a number of manually-labeled social variables acquired using Amazon Me- chanical 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 fea- tures (intensity mean, intensity maximum and syllables per second). We further determine that entrainment is more important to the per- ception of female-male social behavior than it is for same-gender pairs, and it is more impor- tant to the smoothness and flo...
