We identify a set of prosodic cues for parsing con- versational speech and show how such features can be effectively incorporated into a statistical parsing model. On the Switchboard corpus of conversa- tional speech, the system achieves improved parse accuracy over a state-of-the-art system which uses only lexical and syntactic features. Since removal of edit regions is known to improve downstream parse accuracy, we explore alternatives for edit de- tection and show that PCFGs are not competitive with more specialized techniques.
