Abstract
This contribution describes experiments with emotional style conversion performed on the utterances produced by the Czech and Slovak text-to-speech (TTS) system with cepstral description and basic prosody generated by rules. Emotional style conversion was realized as post-processing of the TTS output speech signal, and as a real-time implementation into the system. Emotional style prototypes representing three emotional states (sad, angry, and joyous) were obtained from the sentences with the same information content. The problem with the different frame length between the prototype and the target utterance was solved by linear time scale mapping (LTSM). The results were evaluated by a listening test of the resynthetized utterances.
