Abstract: This paper presents an analysis of the verbal and non-verbal cues of Conversational Agents, with a special focus on REA and GRETA, in order to allow further research aimed at correcting some traits of their performance still considered unnatural by their final users. Despite the striking performance of new generation ECA, some important features make these conversational agents unreliable to the users, who usually prefer interacting with a classical computer for information retrieval. The users' preference can be due to several factors, such as the quality of speech synthesis, or the inevitable unnaturalness of the graphics animating the avatar. Apart from the unavoidable traits that can render ECAs unnatural to the ultimate users, instances of poor synchronization between verbal and non-verbal behaviour may contribute to unfavourable results. An instance of synchronization patterns between non-verbal cues and speech is here analysed and re-applied to the basic architecture of an ECA in order to improve the ECA's verbal and non-verbal synchronization. A proposal for future inquiry aimed at creating alternative model for the ultimate Mp4 output is also proposed, for further development in this field.
