Modeling the Prosody of Hidden Events for Improved Word Recognition
We investigate a new approach for using speech prosody as a knowledge source for speech recognition. The idea is to penalize word hypotheses that are inconsistent with prosodic features such…

Combining Words and Prosody for Information Extraction from Speech
In this work we demonstrate the use of em prosodic cues, alone and in combination with words, for segmentation and name finding. In experiments, we find that prosodic cues alone…
