Resumen:
Synchrony is a form of entrainment which consists in a relativecoordination between two speakers, who throughout conversationsimultaneously vary some properties of their speech. Wedescribe two novel measures of acoustic-prosodic synchronythat are derived from a time-series analysis of the speech signal.Both of these measures reward positive synchrony (entrainment)and, while one penalizes negative synchrony (disentrainment),the other one rewards it. We describe significantcorrelations between the second measure and a number of positivesocial characteristics of the conversations, such as degreeof speaker engagement, in a corpus of task-oriented dialoguesin Standard American English. Since these correlations are notfound to be significant for the first measure, our results suggestthat disentrainment may sometimes have a positive effect on thedevelopment of conversation.
