Prosodic synchrony has been reported to be an important aspect of conversational dyads. In this paper, synchrony in four different dyads is examined. A Time Aligned Moving Average (TAMA) procedure is used to temporally align the prosodic measurements for the detection of synchrony in the dyads. An overlapping windowed correlation procedure is used to(More)
Spoken dialogue systems are increasingly being used to facilitate and enhance human communication. While these interactive systems can process the linguistic aspects of human communication, they are not yet capable of processing the complex dynamics involved in social interaction, such as the adaptation on the part of interlocutors. Providing interactive(More)
Acoustic/prosodic feature (a/p) convergence has been known to occur both in dialogues between humans, as well as in human-computer interactions. Understanding the form and function of convergence is desirable for developing next generation conversational agents, as this will help increase speech recognition performance and naturalness of synthesized speech.(More)
This paper presents methodologies and tools for language resource (LR) construction. It describes a database of interactive speech collected over a three-month period at the Science Gallery in Dublin, where visitors could take part in a conversation with a robot. The system collected samples of informal, chatty dialogue – normally difficult to capture under(More)
RÉSUMÉ Il a été observé dans de nombreuses études qu'un locuteur, au cours d'une conversation, adapte son comportement verbal et non-verbal (lexique, syntaxe, prosodie, postures, gestuelle) à celui de son interlocuteur. Cette adaptation inter-personnelle participe d'une part à faciliter l'échange d'information, la compréhension mutuelle entre interactants(More)

Our research in emotional speech analysis has led to the construction of several dedicated high quality, online corpora of natural emotional speech assets. The requirements for querying, retrieval and organization of assets based on both their metadata descriptors and their analysis data led to the construction of a suitable interface for data visualization(More)
