Filled pauses (FPs) are claimed to occur when speakers have some difficulties and need extra time in speech production. This study investigated whether the following two factors affect silent pause (SP) and FP durations at clause boundaries, using a spontaneous speech corpus: 1) boundary strength and 2) subsequent clause length. First, whether SP and FP durations increase with syntactic boundary strength was examined. Second, whether subsequent clause length affects SP and FP durations at the boundaries was investigated. Results show SP duration increased with boundary strength and subsequent clause length, but FP duration did not, suggesting only SP duration is affected by the two Factors.
