  abstract  = {A common convention in graphical user interfaces is to indicate a "wait
	state", for example while a program is preparing a response, through a changed
	cursor state or a progress bar. What should the analogue be in a spoken
	conversational system?
	To address this question, we set up an experiment in which a human information
	provider (IP) was given their information only in a delayed and incremental
	manner, which systematically created situations where the IP had the turn but
	could not provide task-related information.
	Our data analysis shows that 1) IPs bridge the gap until they can provide
	information by re-purposing a whole variety of task- and grounding-related
	communicative actions (e.g. echoing the user's request, signaling
	understanding, asserting partially relevant information), rather than being
	silent or explicitly asking for time (e.g. "please wait"), and that 2) IPs
	combined these actions productively to ensure an ongoing conversation. These
	results, we argue, indicate that natural conversational interfaces should also
	be able to manage their time flexibly using a variety of conversational
	resources.},
