Hesitations are prevalent in spontaneous speech and believed to be relevant to on-line speech planning. We tested the complexity hypothesis that speakers are more likely to need to suspend speaking, the more complex the constituent, by examining ratios of filled pauses (fillers) at clause and case boundaries with following constituents of different degrees of complexity, using "the Corpus of spontaneous Japanese". The filler ratios were constantly higher as the following constituents were more complex, supporting the hypothesis. The result indicates that fillers can be clues about complexity of the upcoming constituents.
