Integrated recognition of words and phrase boundaries

Florian Gallwitz, Anton Batliner, Jan Buckow, Richard Huber, Heinrich Niemann, Elmar Nöth

In this paper we present an integrated approach for recognizing both the word sequence and the syntactic-prosodic structure of a spontaneous utterance. We take into account the fact that a spontaneous utterance is not merely an unstructured sequence of words by incorporating phrase boundary information into the language model and by providing HMMs to model boundaries. This allows for a distinction between word transitions across phrase boundaries and transitions within a phrase. During recognition, the syntactic-prosodic structure of the utterance is determined implicitly. Without any increase in computational effort, this leads to a 4% reduction of word error rate, and, at the same time, syntactic-prosodic boundary labels are provided for subsequent processing. The boundaries are recognized with a precision and recall rate of about 75% each. They can be used to reduce drastically the computational effort for parsing spontaneous utterances. We also present a system architecture to incorporate additional prosodic information.
