Vocalization–Silence Dynamic Patterns: A system for measuring coordination in psychotherapeutic dyadic conversations

This paper presents the Vocalization–Silence Dynamic Patterns (VSDP) method for the analysis of coordination in psychotherapeutic conversation. The objectives of its development are to empirically account for vocal coordination patterns in dialogs and to examine the association between interactional coordination and positive relational outcomes. The VSDP method makes it possible to demonstrate that vocal activity is a nonverbal phenomenon entwined with and which influences the linguistic code. The analyses which can be carried out through this method are illustrated with real acoustic signals taken from psychotherapy segments. The VSDP method is discussed, considering its usefulness for psychotherapeutic research as well as the study of dyadic conversation within other scenarios.
