The significance of prosody research is not only the contribution to basic knowledge in speech science but also the advancement in speech technology, particularly speech synthesis. A new practice on intonation modeling is to test the models by regenerating the complete acoustic features based on the model and comparing them to the originals. This offer us truly rigorous tests of predictive power of theories and models of speech prosody.

This tutorial will provide a comprehensive procedure for systematically studying prosody based on a user-friendly prosody modeling programs (ProsodyPro, PENTATrainer) that can be used for both analysis and synthesis purposes. ProsodyPro is a Praat-based tool that allows users to perform comprehensive prosody analysis. It is particularly useful for large-scale systematic experimental investigation of prosody. PENTATrainer analyzes F₀ contours based on user-specified functional annotation on the one hand and the program-internal Target Approximation model. The program uses analysis-by-synthesis to determine the optimal parameters for user-defined prosodic categories. By using a stochastic optimization method, the program automatically optimizes the model parameters that can be readily used in synthesis. The same parameters, meanwhile, can also be used as measurements for analysis purposes.
