We present two approaches to generate F0 contours for German utterances based on a phonological transcription of the utterances (phonetic string, accents, and phrase boundaries). The first approach uses a data base of natural F0 patterns which are concatenated to new Fo contours. The second one uses a recurrent neural network to produce global F0 contours directly from the encoded phonological transcription. Our results show that both approaches are well-suited to produce high-quality F0 contours. So far, the resulting contours produced with the neural network are better than the ones produces with the patterns data base. Using a neural network for the generation of complete F0 contours with high quality is feasible and may require much less human effort than other approaches.
