Seminar at Speech, Music and Hearing:

How to build an attentive speaker

a report from eNTERFACE 2010, Amsterdam

Abstract

Face-to-face conversation in a typical task oriented domain may be viewed as a role play where one is having the speaker role and the other is having the listener role. Being an attentive speaker involves many things, but first of all creating opportunities for the listener to give responses, such as “yeah”, “right”, “mhm”, head-nods or other gestures. Many conversational systems operate within the “Walkie-Talkie Turn Taking Paradigm”, i.e. one participant talks while the other is silent, and long response times are not uncommon. To overcome this, an analysis of speech in overlap leads to a cascade of classifiers which can advise the dialog manager whether it is appropriate to speak in overlap or not. It is also preferable to change ongoing behavior according to new circumstances. This requires simultaneous perception/interpretation and production of communicative behaviors. This seminar discusses how to implement these considerations as an upgrade of the Embodied Conversational Agent developed in the SEMAINE project. Finally, a pilot study is presented.
