A Grammar Based Approach to Style Specific Phrase Prediction

Alok Parlikar, Alan W. Black

We present an approach to style specific phrasing for Text-to- Speech (TTS) systems. We formulate the problem of phrase break prediction (or phrasing) as generation of a sequence of breaks (B) and non-breaks (NB) after each word in a sentence. We use prosodic breaks in speech data to build shallow parses over corresponding text. We then learn a grammar that can predict these shallow prosodic parses from text. We then combine this prosodic phrasing information with other word level features in a CART tree to predict where phrase breaks should be inserted in new text. We show that a model built to target a specific reading style can predict phrase breaks more accurately than the standard generic model.
