Syntactic Information and Analysis and Prediction of Prosody Structure

Automatic prosody structure prediction is a very important component in high quality Text-to-Speech systems which directly affect the naturalness and expressivity of synthesized speech.A text corpus with both syntactic and prosodic structures annotated is constructed.Based on the corpus,the composition of prosody structure and the relationship between syntactic and prosodic structures are analyzed,and a prediction experiment is carried out.The result shows that,though there are differences between the prosodic structure and the syntactic structure in Chinese,they have a close relationship the prosodic structure can be predicted by the syntactic structure.The prosodic structure is also affected by the semantic information of the sentence.
