One cue, prosodic disjuncture, is detected by a decision tree-based ensemble classifier that uses acoustic cues to identify where normal prosody seems to be interrupted (Lickley, 1996). The other cue, syntactic parallelism, codifies the expectation that repairs continue a syntactic category that was left unfinished in the reparandum (Levelt, 1983). The two cues are combined in a Treebank PCFG whose states are split using a few simple tree transformations. Parsing performance on the Switchboard and Fisher corpora suggests that these two cues help to locate speech repairs in a synergistic way.}, doi = {10.3115/1220175.1220196}, url = {http://dx.doi.org/10.3115/1220175.1220196}, author = {Hale,John and Shafran,Izhak and Yung,Lisa and Dorr, Bonnie J and Harper,Mary and Krasnyanskaya,Anna and Lease,Matthew and Liu,Yang and Roark,Brian and Snover,Matthew and Stewart,Robin} }
