Experiments with the prediction and generation of Romanian intonation

During the development of a text-to-speech synthesis system, prosody prediction and generation, is one of the most critical phases. Prosody is composed by the melody, intensity and the speed of the speech. The current paper has in focus the intonation of Romanian language, its prediction and generation within a TTS system. During the development of different prosodic modules, several experimental results have been achieved, which are presented in this work. The process is followed starting from text pre-processing, the determination of sentence types and subtypes, through automatic labeling of sentences, till the labeling and transposing of the intonation curves. The creation and storage of relative intonation curves, as the developed different XML rule systems are also topic of this work.
