Abstract: This paper will propose extending the traditional definition of system acceptability to take into account significant interaction between a man and a real or virtual system. We introduce the notion of “socially credible ” which describes the need of emotions and personality in intelligent environment. This notion is measured by experiments using a plush robot Emi and a virtual embodied conversational agent 1

Text and speech corpora for training a tale telling robot have been designed, recorded and annotated. The aim of these corpora is to study expressive storytelling behaviour, and to help in designing expressive prosodic and co-verbal variations for the artificial storyteller). A set of 89 children tales in French serves as a basis for this work. The tales annotation principles and scheme are described, together with the corpus description in terms of coverage and inter-annotator agreement. Automatic analysis of a new tale with the help of this corpus and machine learning is discussed. Metrics for evaluation of automatic annotation methods are discussed. A speech corpus of about 1 hour, with 12 tales has been recorded and aligned and annotated. This corpus is used for predicting expressive prosody in children tales, above the level of the sentence.

Abstract. In this article, we present current work being developed in collaboration between UFRGS (Brazil) and LIG laboratory (France) inserted in the scope of PRAIA Project -international project of cooperation between UFRGS and LIG. We first motivate the use of Embodied Conversational Agents (ECAs) by showing and contextualizing research, in order to establish a foundation for understanding how these agents may be useful in human-computer interaction. We then give more details about the agent, its purpose and scenario, together with important characteristics of its development. Finally we conclude with more information about the cooperation and also demonstrating the importance of the research in this field.
Session 2: Tuning Communication in Face-to-Face Interaction Towards Expressive Communication in Embodied Conversational Agents

Embodied Conversational Agents (also known as ECA) are animated software agents (usually very similar to the human figure) which represent the possibility of extending the aim of common conversation systems and perform non appropriate verbal behavior, such as facial expressions, looks, gestures and ..."

Embodied Conversational Agents (also known as ECA) are animated software agents (usually very similar to the human figure) which represent the possibility of extending the aim of common conversation systems and perform non appropriate verbal behavior, such as facial expressions, looks, gestures and processing of natural language in all its levels, contributing to a better understanding of a
