Belz, Malte; Reichel, Uwe D. (2015): Pitch characteristics of filled pauses in spontaneous speech. DiSS 2015: Disfluency in Spontaneous Speech, 8. - 9. August 2015, Edinburgh, Scotland.


We investigate the pitch characteristics of filled pauses in order to distinguish between hesitational and floor-holding functions of filled pauses. A corpus of spontaneous dialogues is explored using a parametric bottom-up approach to extract intonation contours. We find that subjects tend to utter filled pauses more prominently when they cannot see each other, which indicates an increased floor-holding usage of filled pauses in this condition.
