Abstract

Automatic measurement of prosodic accommodation in conversational interaction It has been observed in many studies that speakers, over the course of a conversation, adapt their verbal and non-verbal behaviour (lexicon, syntax, prosody, postures, gesture) to their interlocutor. This accommodation facilitates, on the one hand, the exchange of information, mutual understanding between interactants and the reaching of common ground. Moreover, it increases the social success of the interaction in terms of rapport (i.e. harmonious relation and mutual attention) and affiliation. While accommodation is a ubiquitous component of social interaction, few automatic systems and metrics have been developed to quantify it. In this paper, we present a model which provides metrics for the automatic measurement of prosodic accommodation and its dynamic manifestation in conversation. Based on this model, we discuss the different forms and the dynamics of prosodic accommodation, measured from conversations recorded over a period of several months. MOTS-CLÉS : Adaptation prosodique, dynamiques de la parole, interaction sociale. KEYWORDS: Prosodic adaptation, speech dynamics, social interaction. 321 1

Cette adaptation inter-personnelle participe d’une part à faciliter l’échange d’information, la compréhension mutuelle entre interactants et l’atteinte d’un terrain commun. D’autre part, elle augmente chez les acteurs le sentiment d’une interaction sociale réussie en termes de rapport (i.e. relation harmonieuse et attention mutuelle) et d’appartenance sociale. Si l’adaptation inter-personnelle est un phénomène omniprésent de l’interaction conversationnelle, peu de systèmes automatiques et de métriques ont été développés pour la quantifier. Dans cet article, nous présentons un modèle qui permet de mesurer automatiquement l’adaptation prosodique et ses dynamiques en conversation. Sur la base de ce modèle, nous discutons les différentes formes et les dynamiques de l’adaptation prosodique mesurées à partir de conversations téléphoniques enregistrées sur une période de plusieurs mois.

Si ces systèmes sont capables de traiter la composante linguistique de la communication humaine, ils ne peuvent en revanche toujours pas traiter les dynamiques complexes et les ajustements inter-locuteurs qu’implique l’interaction. 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 (Giles et al., 1991; Brennan, 1996; Coulston et al., 2002; Richardson et al., 2007).

Automatic measurement of prosodic accommodation in conversational interaction It has been observed in many studies that speakers, over the course of a conversation, adapt their verbal and non-verbal behaviour (lexicon, syntax, prosody, postures, gesture) to their interlocutor. This accommodation facilitates, on the one hand, the exchange of information, mutual understanding between interactants and the reaching of common ground. Moreover, it increases the social success of the interaction in terms of rapport (i.e. harmonious relation and mutual attention) and affiliation. While accommodation is a ubiquitous component of social interaction, few automatic systems and metrics have been developed to quantify it. In this paper, we present a model which provides metrics for the automatic measurement of prosodic accommodation and its dynamic manifestation in conversation. Based on this model, we discuss the different forms and the dynamics of prosodic accommodation, measured from conversations recorded over a period of several months.
