Venue Annual Meeting of the Association of Computational Linguistics

We describe the modification of a grammar to take advantage of prosodic information provided by a speech recognition system. This initial study is lim- ited to the use of relative duration of phonetic seg- ments in the assignment of syntactic structure, specif- ically in ruling out alternative parses in otherwise ambiguous sentences. Taking advantage of prosodic information in parsing can make a spoken language system more accurate and more efficient, if prosodic- syntactic mismatches, or unlikely matches, can be pruned. We know of no other work that has suc- ceeded in automatically extracting speech informa- tion and using it in a parser to rule out extraneous parses.
