This paper introduces the Common Prosody Platform (CPP), a computational platform that implements major theories and models of prosody. CPP aims at a) adapting theory-specific assumptions into computational algorithms that can generate surface prosodic forms, and b) making all the models trainable through global optimization based on automatic analysis-by-synthesis learning. CPP allows examination of prosody in much finer detail than has been previously done and provides a means for speech scientists to directly compare theories and their models. So far, four theories have been included in the platform, the Parallel Encoding and Target Approximation model, the Autosegmental-Metrical theory, the Task Dynamic model, and the Command-Response model. Preliminary tests show that all the implemented models can achieve good local contour fitting with low errors and high correlations.
