This paper presents a conditional ran- dom field-based approach for identifying speaker-produced disfluencies (i.e. if and where they occur) in spontaneous speech transcripts. We emphasize false start re- gions, which are often missed in cur- rent disfluency identification approaches as they lack lexical or structural similar- ity to the speech immediately following. We find that combining lexical, syntac- tic, and language model-related features with the output of a state-of-the-art disflu- ency identification system improves over- all word-level identification of these and other errors. Improvements are reinforced under a stricter evaluation metric requiring exact matches between cleaned sentences annotator-produced reconstructions, and altogether show promise for general re- constructio...
