We describe the modification of a grammar to take advantage of prosodic information automatically extracted from speech. The work includes (1) the development of an integer "break index" representation of prosodic phrase boundary information, (2) the automatic detection of prosodic phrase breaks using a hidden Markov model on relative duration of phonetic segments, and (3) the integration of the prosodic phrase break information in SRI's Spoken Language System to rule out alternative parses in otherwise syntactically ambiguous sentences. Initial experiments using ambiguous sentences read by radio announcers achieved good results in both detection and parsing. Automatically detected phrase break indices had a correlation greater than 0.86 with hand-labeled data for speaker-dependent models; and, in a subset of sentences with preposition ambiguities, the number of parses was reduced by 25% with a simple grammar modification.
