Convergence of fundamental frequencies in conversation: if it happens, does it matter?

This paper explores the existence and nature of accommodation processes within conversation, particularly convergence of fundamental frequency (Fo) of conversational participants over time. The study raises a number of issues related to methodologies for analysing interactional (typically conversational) data. Most important is the issue of the applicability of statistical sampling methods which are independent of the interactional events occurring within the talk. It concludes with suggestions for a methodology that examines long term acoustic phenomena (eg long term fundamental frequency) and relates events at the micro acoustic level to interactional events within a conversation.
