Mandarin prosodic models are very important in speech research and synthesis, which mainly describes the variation of pitch. The models that are now being used in most Chinese Text-To=Speech systems. In this paper, we propose a Multi-stategy Data Mining framework to extract prosodic patterns from actual large Mandarin speech database to improve the naturalness and intelligibility of synthesized speech. In data preprocessing, typical prosody models are found by clustering analysis, and Rough Set is employed for feature selection. ANN and Decision tree are trained respectively. The prediction result of ANN and Decision Tree are integrated to generate fundamental frequency and energy contours. The experimental results showed that synthesized prosodic features quite resembled their original counterparts for most syllables.
