Sažetak
Text-to-speech systems convert text into speech. Synthesized speech without prosody sounds unnatural and monotonous. In order to sound natural, prosodic elements have to be implemented. The generation of prosodic elements directly from text is a rather demanding task. Our final goals are building a complete prosodic model for Croatian and implementing it into our TTS system. In this work, we present one of the steps in implementation of prosody into TTSs – detection of intonation events using Tilt intonation model. We propose a training procedure which is composed of several subtasks. First, we hand-labelled a set of utterances and within each of them, marked four types of prosodic events. Then we trained HMMs and used them to mark prosodic events on a larger set of utterances. Finally, we assigned parameters to each of the event and generated f0 contours from the parameters .We evaluated the obtained f0 contours.
