  abstract  = {We consider the automatic scoring of a task for which both the content of the
	response as well its spoken fluency are important. We combine features from a
	text-only content scoring system originally designed for written responses with
	several categories of acoustic features. Although adding any single category of
	acoustic features to the text-only system on its own does not significantly
	improve performance, adding all acoustic features together does yield a small
	but significant improvement. These results are consistent for responses to
	open-ended questions and to questions focused on some given source material.},
