How can you use disfluencies and still sound as a good speaker?

This paper explores the results of a previous experiment concerning listeners ’ ratings of different types of (dis)fluencies and extends the analysis of such phenomena to a corpus of university lectures. Results suggest that, although not all disfluency types are equally tolerated by listeners, such differences may be overridden by an adequate control of tonal scaling and pause length, at least. Index Terms: disfluencies, prosody, fluency ratings. 1
