Prosodic patterns provide important cues for resolving syntactic ambiguity, and can be used to improve the accuracy of automatic speech understanding. With this goal, we propose a method of scoring syntactic parses in terms of observed prosodic cues, which can be used in ranking sentence hypotheses and associated parses. Specifically, the score is the probability of a hypothesized word sequence and associated syntactic parse given acoustic features, based on acoustic and "language" (prosody/syntax) models that represent probabilities in terms of abstract prosodic labels. Experimental results on a corpus of ambiguous sentence pairs indicate that the algorithm achieves disambiguation performance close to that of human listeners.
