Our research group has postulated a perceptually based multiphrase prosody framework for speech paragraphs in fluent speech using corporal analyses. The framework features a prosody hierarchy that organizes phrases and sentences into prosodic groups (PG) in connected speech, and specifies cross-phrase prosodic relationships in the acoustic domains [1, 2] . A corresponding fluent speech prosody model with four independent acoustic modules was also constructed [3] . The model predicts

Cumulative results from each and every prosody layer accounts for overall output prosody. We have since improved the model first by refining the duration and intensity modules through corpus analysis, and subsequently used the above improved results to facilitate better pause/break predictions. As a result, the enhanced model is now more robust than its initial version. Future works will focus on applying the improved model to synthesis of fluent connected speech.
