intonation modeling

For some time the group has been involved in projects on data-driven prosodic modeling for a text-to-speech synthesis. Our prosodic modeling approach starts with the prediction of word prominence values (PRM) for each word of the text and prosodic boundary strength values (PBS) between successive words of that text. The next step is the derivation of good intonation and phoneme duration patterns from that information. Two different methods of intonation modeling were developed and compared:
