Abstract [en]

A basic requirement for participation in conversation is the ability to jointly manage interaction, and to recognize the attempts of interlocutors to do same. Examples of management activity include efforts to acquire, re-acquire, hold, release, and acknowledge floor ownership, and they are often implemented using dedicated dialog act types. In this work, we explore the prosody of one class of such dialog acts, known as floor mechanisms, using a methodology based on a recently proposed representation of fundamental frequency variation. Models over the representation illustrate significant differences between floor mechanisms and other dialog act types, and lead to automatic detection accuracies in equal-prior test data of up to 75%. description of floor mechanism prosody. We note that this work is also the first attempt to compute and model FFV spectra for multiparty rather than two-party conversation, as well as the first attempt to infer dialogue structure from non-anechoic-chamber recordings.
