Modeling and Synthesizing Emotional Speech for Catalan Text-to-Speech Synthesis

This paper describes an initial approach to emotional speech synthesis in Catalan based on a diphone concatenation TTS system. The main goal of this work is to develop a simple prosodic model for expressive synthesis. This model is obtained from an emotional speech collection artificially generated by means of a copy-prosody experiment. After validating the emotional content of this collection, the model was automated and incorporated into our TTS system. Finally, the automatic speech synthesis system has been evaluated by means of a perceptual test, obtaining encouraging results.
